Division

1. Division Pamela Leutwyler

2. The base ten division algorithm relies upon your knowledge of base ten multiplication facts. For example: You begin this problem by noting that 23 goes into 71 three times – you can do this easily because you once memorized “3x2 = 6” and “4x2 = 8” Because you have never memorized multiplication facts in bases other than ten, before you can begin a long division problem, you must list the single digit multiples of your divisor:

5. example 1: 3 too big

6. example 1: 3 multiply

7. example 1: 3 subtract in base 5

8. example 1: 3 13 6 subtract in base 5 1

9. example 1: 3 134 bring down the 4

10. example 1: 4 3 134 21 goes into 134 four times

11. example 1: multiply 4 3 134 134
