How do you do long division?

Long division satisfies dividend = divisor × quotient + remainder, processing the dividend digit by digit. At each step you take the carried remainder, bring down the next digit, divide by the divisor for the next quotient digit, then subtract to find the new remainder. For example, 1234 ÷ 7 = 176 remainder 2, because 7 × 176 + 2 = 1234.

Understanding your result

At each step you take the carried remainder, bring down the next digit, divide by the divisor to get the next quotient digit, then subtract to find the new remainder. The final remainder is what is left over.

Formula and method

dividend = divisor × quotient + remainder. Long division processes the dividend digit by digit, dividing the running value by the divisor and carrying the remainder forward.

Worked example

1234 ÷ 7 = 176 remainder 2, because 7 × 176 + 2 = 1234.

Frequently asked questions

What is the quotient and remainder?

The quotient is how many whole times the divisor goes into the dividend; the remainder is what is left over and is always smaller than the divisor.

Does it handle large numbers?

Yes, up to very large whole numbers. For decimal answers, the calculator also shows the exact decimal value.
