125 ÷ 7
17 R 6
Decimal: 17.8571
Step-by-step working
- 1. Bring down 1 → 1: smaller than 7, write nothing yet, carry 1 over.
- 2. Bring down 2 → 12: 7 × 1 = 7; 12 − 7 = 5.
- 3. Bring down 5 → 55: 7 × 7 = 49; 55 − 49 = 6.
- 4. Check: 17 × 7 + 6 = 125. ✓

About this Tool
Long division breaks a tricky division into small bring-down, multiply and subtract stages you can follow digit by digit. Enter any dividend and divisor to get the quotient and remainder alongside every numbered working step in plain monospaced text. Switch on the decimal view to see the full decimal answer too.
Common Use Cases
Homework Help
Check school division problems and see exactly where each digit of the answer comes from.
Verify Mental Math
Confirm a head-calculation by comparing it against the full written working.
Learn Place Value
Watching digits get carried down shows why each quotient digit sits where it does.
Remainder Problems
Splitting items into equal groups leaves a remainder — see it computed explicitly.
Pro Tips
- !
Divisor Can't Be Zero
Division by zero is undefined, so the divisor must be 1 or more — the tool will tell you otherwise.
- !
Line Digits Up
In written work, keep each subtract step aligned under the right digits to avoid place-value slips.
- !
Always Run the Check
Multiply quotient × divisor and add the remainder — it must equal your starting dividend.
