Long Division Calculator — Step-by-Step Division Solver
This free Long Division Calculator helps you divide large numbers quickly and accurately. It shows each step of the long division process, including partial dividends, subtractions, and the final quotient and remainder. Designed for students, teachers, and anyone learning manual division, it follows the classic long division method used worldwide in schools.
How the Long Division Calculator Works
Long division is a systematic method for dividing large numbers into smaller, easier steps.
The calculator uses the standard arithmetic identity:
Dividend = (Divisor × Quotient) + Remainder.
Each stage of division repeats this process — multiply, subtract, and bring down the next digit —
until no digits remain or the remainder is smaller than the divisor. This method is detailed on

Formula Used in Long Division
The mathematical basis for long division follows this formula:
Quotient = Dividend ÷ Divisor
Remainder = Dividend − (Divisor × Quotient)
Step-by-Step Example
Let’s divide 1256 by 12:
1️⃣ Divide: 12 goes into 125 ten (10) times.
2️⃣ Multiply: 12 × 10 = 120.
3️⃣ Subtract: 125 − 120 = 5.
4️⃣ Bring down next digit (6): now 56 ÷ 12 = 4 (remainder 8).
✅ Final Answer: 1256 ÷ 12 = 104 R8.
