Maths worksheet: Long division p2

long-division-2The second in our series of long division pages. These are very hard for primary school children and should not be attempted until they have a good knowledge of tables, multiplying and subtraction.

Example: 789 divided by 36.

First carry out an estimate of the answer. I think 789 divided by 36 is about 20.
Then proceed using these steps:
1. How many 36s in 78?
2. 2 x 36 is 72.    3 x 36 is 108 which is too many, so it must be 2.
3. Put the 2 in the tens column above the answer.
4. Place the 72 below the 78 and subtract.
5. 78 – 72 is 6.
6. ‘Bring down’ the 9 to make 69.
7. How many 36s in 69.
8. By trial and improvement and some rough work multiplying 36 by my estimated numbers I find that 36 x 1 = 36.
9. Place the 36 under the 69 and subtract.
10. The remainder (33) must be less than the original number you are dividing by.
