1-11. LONG DIVISION
There are several techniques for doing long division. You may be used to a
different technique from the one shown below. If you prefer another way, use it.
EXAMPLE: Divide 875 by 25.
35
25)875
75
125
125
0
STEPS followed in the problem above:
(1)
Try to divide 25 into 87. About how many times will 25 go into 87?
The answer is more than 3 but less than 4.
_____
25)875
(2)
Write down 3 in the space for the quotient, directly above the 7.
3
25)875
(3)
Now multiply 3 x 25 and write the answer under the 87. (3 x 25 = 75)
Write 75 under the 87.

25)875
75
(4)
Subtract 75 from 87. The difference is 12. Write 12 directly under the
75.
3
25)875
75
12
(5)
Now "bring down" the 5 from the dividend. The 12 becomes 125.
