AI Math SolverA long division calculator divides multi-digit numbers and lays out every step. Enter the dividend and divisor to see the quotient, remainder, and the full written working.
Long division breaks a large division into a sequence of smaller ones, working one digit of the dividend at a time from left to right. It works for whole numbers and decimals alike.
Each cycle has four moves — divide, multiply, subtract, bring down — repeated until every digit is used. The calculator shows the full scaffold so you can follow along or check your own work.
Set up dividend ÷ divisor. Divide, multiply to find how much of the dividend you covered, subtract to find the remainder, then bring down the next digit and repeat.
When the division does not finish, the leftover is the remainder. It can be written as a whole-number remainder, a fraction (remainder over divisor), or a decimal.
