Long Division Calculator with Steps
Solve long division step by step and show the answer as a remainder or decimal.
Use the arrows to move through the problem the same way it is worked out on paper. The active number is highlighted while the explanation tells you what to do next.
1547 = 12 × 128 + 11

Work long division the same way it is done on paper.
Long division repeats four moves: divide to find the next quotient digit, multiply that digit by the divisor, subtract to find what remains, and bring down the next digit. The guided school method reveals each move in order while keeping every digit aligned by place value.
Use remainder mode when the answer should stop with a whole-number remainder. Use decimal mode to continue by bringing down zeros after the decimal point. The walkthrough also identifies repeating decimals when a remainder cycle repeats.
How to use the long division calculator
1. Enter the dividend, which is the number being divided, and the divisor, which is the number you are dividing by. 2. Choose remainder mode for a whole-number quotient with a remainder or decimal mode to continue past the decimal point. 3. Select Show the Work. 4. Use the arrows beside the school-method layout to move through each divide, multiply, subtract, and bring-down step one at a time.
Long division examples with remainders and decimals
1547 ÷ 12 = 128 remainder 11. The check is 12 × 128 + 11 = 1547. This is a useful example for seeing several bring-down steps.
625 ÷ 4 = 156.25. Remainder mode stops at 156 remainder 1, while decimal mode continues the same long-division process by bringing down zeros.
1 ÷ 3 = 0.333…. When the same nonzero remainder appears again, the decimal repeats. The calculator identifies that cycle instead of pretending the decimal terminates.
Long division questions students often ask
What are the dividend and divisor? The dividend is the number being split or divided. The divisor is the number you divide by. In 1547 ÷ 12, 1547 is the dividend and 12 is the divisor.
How do you check a remainder? Multiply the divisor by the whole-number quotient and add the remainder. The result should equal the original dividend.
Can long division give a decimal answer? Yes. If a remainder remains, add a decimal point and continue the same divide-multiply-subtract-bring-down pattern using zeros.
