How it works
Each bracket on these partial quotient division worksheets has a side column for the chunks. The page opens on 3-digit ÷ 1-digit, such as 738 ÷ 6 = 123; the largest sheet reaches 5,000 ÷ 48 = 104 R 8.

How partial quotients works
Pupils take away easy multiples of the divisor and keep a tally of groups down the side. For 738 ÷ 6, take 600 and write 100 in the side column. Take 120 from the 138 left and write 20. Take the last 18 and write 3. The column adds up to 100 + 20 + 3 = 123. Smaller chunks reach the same answer in more lines.
Chunking, hangman and other names
British primary schools call the method chunking. With a line between the working and the partial quotients it is also called the hangman method. England's curriculum sets out its long division example, 432 ÷ 15, in chunks: it subtracts 300 and 120 and notes 15 × 20 and 15 × 8 beside them.
- Print Easy multiples of the divisor: × 2, × 5, × 10, × 20 first: those products are the chunks.
- A pupil who takes 10 groups again and again is ready for Fewest chunks: hundreds, tens, ones.
- Repeated subtraction, one group at a time shows what the side column counts: groups of the divisor.
Questions and answers
What grade is partial quotients division?
The number sizes are grades 4 and 5. Common Core 4.NBT.6 asks for quotients and remainders with up to 4-digit dividends and 1-digit divisors, using strategies based on place value. 5.NBT.6 moves to 2-digit divisors. Neither names a method; partial quotients is one such strategy.
How do you do partial quotients with a remainder?
Keep taking chunks until what is left is smaller than the divisor. For 95 ÷ 4, take 40, 40 and 12. The side column adds up to 23 and 3 is left: 23 R 3. Check: 23 × 4 + 3 = 95.
Which chunks should pupils take away?
Any multiple of the divisor they are sure of. Times 10, 5 and 2 are the usual picks: for 945 ÷ 27 that makes 270, 135 and 54. The key heads its chunks One way: any set adding up to the quotient is right.
Is partial quotients the same as long division?
Long division takes the largest chunk at each place, so 952 ÷ 7 goes 700, 210, 42. Partial quotients allows any. The side column makes a lost zero easy to spot: No tens chunk: quotients like 206 has 824 ÷ 4 = 200 + 6.
