Long Division Calculator
Long Division Calculator
Enter a dividend and a divisor. This walks through the classic long division algorithm digit by digit — bringing down each digit, dividing, and tracking the remainder — and shows the quotient, remainder, and full decimal result.
Long division processes the dividend one digit at a time: at each step, the next digit is brought down alongside the running remainder, divided by the divisor, and the result recorded before moving on — the same method taught in school, just carried out automatically. The quotient is the whole-number result and the remainder is whatever's left over that doesn't divide evenly; the calculator also converts that remainder into a full decimal continuation, useful for checking long division homework or getting a precise decimal result without a separate calculation.
- How long division works: process the dividend one digit at a time, bringing each digit down alongside the running remainder, dividing by the divisor, and recording the result before moving to the next digit.
- Quotient and remainder: the quotient is the whole-number result of the division, and the remainder is what's left over — dividend = divisor × quotient + remainder.
- Decimal result: continuing the division past the remainder (by adding decimal places) gives the exact or repeating decimal value, shown alongside the whole-number quotient and remainder.
Why learn long division if calculators can do it instantly?
Long division builds the foundational understanding of how division actually works with multi-digit numbers, and it's still needed for dividing polynomials and other algebra later on — this tool shows the steps specifically to support that learning.
What does the remainder actually represent?
It's the amount left over that doesn't divide evenly — for example, 1234 ÷ 7 leaves a remainder of 2 because 7 × 176 = 1232, which is 2 short of 1234.
