Simple Division 137
Nine is 1 below 10, so we write 1 in the circle below the 9. Add the 1
to the tens digit (7) to get an answer of 8. Write 8 as the answer above
the 5. Draw a circle above the 8. How many more to make 10? Th e
answer is 2. Write 2 in the circle above the 8. Multiply the numbers
in the circles, 1 × 2, to get 2. Take 2 from the units digit (5) to get the
remainder, 3. Th e answer is 8 r3.
Here is another example that will explain what we do when the
result is too high.
7
8 52
2
Eight is 2 below 10, so we write 2 in the circle. Two plus 5 equals 7.
We write 7 above the units digit. We now draw another circle above
the 7. How many to make 10? Th e answer is 3, so we write 3 in the
circle. To get the remainder, we multiply the two numbers in the
circles and take the answer from the units digit. Our work should
look like this:
3
7
8 52
2
2 × 3 = 6
We fi nd, though, that we can’t take 6 from the units digit, 2. Our
answer is too high. To rectify this, we drop the answer by 1 to 6, and
write a small 1 in front of the units digit, 2, making it 12. Six is 4
below 10, so we write 4 in the circle.
