125 ÷ 7

17 R 6

Decimal: 17.8571

Step-by-step working

  1. 1. Bring down 1 → 1: smaller than 7, write nothing yet, carry 1 over.
  2. 2. Bring down 2 → 12: 7 × 1 = 7; 12 − 7 = 5.
  3. 3. Bring down 5 → 55: 7 × 7 = 49; 55 − 49 = 6.
  4. 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.
