A) Subtract 6 from 48. If the result less than 6 or 0 you made a mistake. Result is 42. Hence start a counter with a value of 1.
B) Subtract 6 from 42. If the result less than 6 or 0 you made a mistake. Result is 36. Hence increment the counter by 1. Now counter value is 2.
C) Subtract 6 from 36. If the result less than 6 or 0 you made a mistake. Result is 30. Hence increment the counter by 1. Now counter value is 3.
D) Subtract 6 from 30. If the result less than 6 or 0 you made a mistake. Result is 24. Hence increment the counter by 1. Now counter value is 4.
E) Subtract 6 from 24. If the result less than 6 or 0 you made a mistake. Result is 18. Hence increment the counter by 1. Now counter value is 5.
F) Subtract 6 from 18. If the result less than 6 or 0 you made a mistake. Result is 12. Hence increment the counter by 1. Now counter value is 6.
G) Subtract 6 from 12. If the result less than 6 or 0 you made a mistake. Result is 6. Hence increment the counter by 1. Now counter value is 7.
H) Subtract 6 from 6. If the result is not 0 you made a mistake. Result is 0. Hence increment the counter by 1. Now counter value is 8. Since we have nothing more to subtract from stop the process. The last value of the counter was 8 and so the quotient is 8.

5 divided by 5, plus 5
To explain subtraction using the "ten to the top and ten to the bottom" method, start by illustrating how we can borrow from the next column to make subtraction easier. For example, if you have 52 - 28, you can take 10 from the 50 (making it 40) and add it to the 2 (making it 12). Now you can subtract 12 - 8 easily, which equals 4, and then subtract the tens: 40 - 20 equals 20. Finally, combine the results to find that 52 - 28 equals 24.
