Written explanation

  1. 1How many times does 7 go into 81 time. 7 × 1 = 7. 8 − 7 = 1. Bring down the next digit.
  2. 2How many times does 7 go into 142 times. 7 × 2 = 14. 14 − 14 = 0. Bring down the next digit.
  3. 3How many times does 7 go into 50 times. 7 × 0 = 0. 5 − 0 = 5.
  4. No more digits to bring down. Final remainder: 5.

How Long Division Works

Long division breaks a large division problem into a sequence of smaller steps. For each digit of the dividend you find how many times the divisor fits, multiply back, subtract, and bring down the next digit — repeating until all digits are used. Whatever is left at the end is the remainder.

The Long Division Calculator shows you every step of the long division process in plain language. Enter any two whole numbers and instantly see how many times the divisor fits into each portion of the dividend, the subtraction at each stage, and the final quotient with remainder. Great for checking homework, teaching the method, or brushing up on arithmetic fundamentals.

FAQ
What is a remainder in long division?+

The remainder is what is left over after the divisor no longer fits into the dividend evenly. For example, 845 ÷ 7 = 120 remainder 5, because 7 × 120 = 840 and 845 − 840 = 5.

Can I divide negative numbers?+

Yes. The calculator accepts negative integers. The sign of the quotient follows the standard rule: dividing a negative by a positive (or a positive by a negative) produces a negative quotient. The remainder is always shown as a non-negative value.

What if the divisor is larger than the dividend?+

When the divisor is larger than the dividend the quotient is 0 and the dividend itself becomes the remainder. For example, 3 ÷ 9 = 0 remainder 3.

How can I verify the answer?+

Use the verification identity: divisor × quotient + remainder = dividend. The calculator displays this check automatically so you can confirm the result is correct.
