Divides two whole integers, a dividend and a divisor, and express the answer as a whole number quotient, along with a whole number remainder. This is one of two long division methods, and is simpler than producing a quotient with a decimal. You can practice your math problems then use this calculator to see how to do the long division and check against your answers.

For the division problem 487 ÷ 32 = 15 R 7, 487 is the dividend, 32 is the divisor, 15 is the quotient and 7 is the remainder.
From the example above, let's say we wanted to divide 487 by 32, showing our work. How would we do it?
|We set up our problem with the long division symbol or the long division bracket. Put the dividend on the inside and the divisor on the outside, left.|
|Divide the first number of the dividend by the divisor. You can note the remainder but ignore it for now.||4 ÷ 32 = 0
with a remainder of 4
|The whole number result, 0, is placed on top to start the quotient. That number is then multiplied by the divisor. The result is placed under the number we just divided into.||32 * 0 = 0|
|Next, subtract the bottom number from the top.||4 - 0 = 4|
|Next, we bring down the next number of the dividend.||48|
|We now divide this number (48) by the divisor (32). Again, You can note the remainder but ignore it for now.
Note that you could skip all of the previous steps with zeros and jump straight to this one if you realize how many digits in the dividend you need to get your first non-zero value in the quotient. In this case you would divide 32 into 48 straight away.
|48 ÷ 32 = 1
with a remainder of 16
|The whole number result (1) of this equation is placed in the second position of the quotient. Like the first go around, we then multiply that number by the divisor. Again, the result is placed under the number divided into.||32 * 1 = 32|
|Subtract the product, 32, from the number above it.||48 - 32 = 16|
|Bring down the next number from the dividend.||167|
|Divide this number (167) by the divisor (32). See a pattern emerging?||167 ÷ 32 = 5
with a remainder of 7
|The whole number result (5) of this equation is placed in the next position of the quotient. Just like before, multiply that number by the divisor. Again, the result is placed under the number divided into.||32 * 5 = 160|
|Subtract the result from the number above||167 - 160 = 7|
|As this is the last number, the amount left over (7) is the remainder and the quotient is 15. We're all done.||487 ÷ 32 = 15
with a remainder of 7
For longer dividends, we would simply continue repeating these steps until every digit is brought down from the divdend.
