# Remainder Calculator

This quotient and remainder calculator helps you **divide any number by an integer and calculate the result in the form of integers**. In this article, we will explain to you how to use this tool and what are its limitations. We will also provide you with an example that will better illustrate its purpose.

## Dividend, divisor, quotient, and remainder

When you perform division, you can typically write down this operation in the following way:

`a/n = q + r/n`

where:

`a`

— Initial number you want to divide, called the**dividend**;`n`

— Number you divide by; it is called the**divisor**;`q`

— Result of division rounded down to the nearest integer; it is called the**quotient**; and`r`

—**Remainder**of this mathematical operation.

When performing division with our calculator with remainders, it is important to remember that all of these values must be integers. Otherwise, the result will be correct in the terms of formulas, but will not make mathematical sense.

Make sure to check our modulo calculator for a practical application of the calculator with remainders.

🔎 If the remainder is zero, then we say that **a is divisible by n**. To learn more about this concept, check out Omni's divisibility test calculator.

## How to calculate the remainder

- Begin with writing down your problem. For example, you want to
**divide 346 by 7**. - Decide on which of the numbers is the dividend, and which is the divisor. The
**dividend**is the number that the operation is performed on – in this case,`346`

. The**divisor**is the number that actually "does the work" – in this case,`7`

. - Perform the
**division**– you can use any calculator you want. You will get a result that most probably is not an integer – in this example,`49.4285714`

. **Round**this number down. In our example, you will get`49`

.**Multiply**the number you obtained in the previous step by the divisor. In our case,`49 * 7 = 343`

.**Subtract**the number from the previous step from your dividend to get the remainder:`346 - 343 = 3`

.- You can always
**use our calculator**with remainders instead and save yourself some time 😀

## FAQ

### How do you solve Chinese remainder theorem problems?

- Make sure you have an unknown
**equal to two or more different modulos**, e.g.,`x = d mod a`

,`e mod b`

&`f mod c`

. - Check that all modulos have the
**same greatest common divisor**. - Multiply each modulo by all but one other modulo,
**until all combinations are found**. For the above moduli, this would be:`b*c`

,`a*c`

,`a*b`

. **Divide each number by the modulo that it is missing**. If it equals the remainder for that modulo, e.g.,`(b*c)/a = d`

, leave the number as is.- If the
**remainder is not that for the modulo**, use trial and error to find a positive integer to multiply the number by so that step 4 becomes true. **Add**all numbers together once step 4 is true for all combinations.

### What are some remainder tricks?

It's useful to remember some remainder shortcuts to save you time in the future. First, if a number is being **divided by 10**, then the remainder is just **the last digit of that number**. Similarly, if a number is being **divided by 9, add each of the digits to each other until you are left with one number** (e.g., 1164 becomes 12 which in turn becomes 3), which is the remainder. Lastly, you can **multiply** the decimal of the quotient by the divisor to get the remainder.

### How do I interpret the remainder?

Learning how to calculate the remainder has **many real-world uses** and is something that school teaches you that you will definitely use in your everyday life. Let’s say **you bought 18 doughnuts** for your friend, but **only 15 of them showed up, you’d have 3 left**. Or how much money did you have left after buying the doughnuts? If the maximum number of monkeys in a barrel is 150, and there are 183 monkeys in an area, **how many monkeys will be in the smaller group?**

### How do you turn a remainder into a decimal?

- Set up your division,
**adding**a decimal place followed by a zero after the dividend’s one’s column (if your dividend is already a decimal, add an additional zero to the end). **Perform the division as usual**until you are left with the remainder.- Instead of writing the remainder after the quotient,
**move the remainder above the additional zero**you placed. - If there is a remainder from this division,
**add another zero**to the dividend and add the remainder to that. **Continue in this fashion until**there is either: no remainder, the digit or digits repeat themselves endlessly, or you reach the desired degree of accuracy (3 decimal places is usually okay).- The result after the decimal place is the remainder as a decimal.

### What is the quotient and the remainder?

The **quotient** is **the number of times a division is completed fully**, while the **remainder** is the amount left **that doesn’t entirely go into the divisor**. For example, 127 divided by 3 is **42 R 1**, so 42 is the quotient, and 1 is the remainder.

### How do you write a remainder as a fraction?

Once you have found the remainder of a division, instead of writing R followed by the remainder after the quotient, simply **write a fraction where the remainder is divided by the divisor of the original equation**. It's that easy!

### How do you write remainders?

There are **3 ways** of writing a remainder: **with an R, as a fraction, and as a decimal**. For example, 821 divided by 4 would be written as **205 R 1** in the first case, **205 ^{1}/_{4}** in the second, and

**205.25**in the third.

### What is the remainder when 26 is divided by 6?

The remainder is **2**. To work this out, find the largest multiple of 6 that is less than 26. In this case, it’s 24. Then **subtract** the 24 from 26 to get the remainder, which is 2.

### What is the remainder when 599 is divided by 9?

The remainder is **5**. To calculate this, first, **divide** 599 by 9 to get the largest multiple of 9 before 599. 5/9 < 1, so **carry** the 5 to the tens, 59/9 = 6 r 5, so **carry** the 5 to the digits. 59/9 = 6 r 5 again, so the largest multiple is 66. **Multiply** 66 by 9 to get 594, and **subtract** this from 599 to get 5, the remainder.

### How do I calculate the remainder of 24 divided by 7?

**Subtract 7 from 24 repeatedly**until the result is less than 7.- 24 minus 3 times 7 is
**3**. - The number that is left,
**3**, is the remainder. - This can be expressed as
in fractional form, or as^{3}/_{7}**0.42857**in decimal form.
