I need how to divide fast

10 if the number ends in 0

9 when the digits are added together and the total is evenly divisible by 9

8 if the last three digits are evenly divisible by 8 or are 000

6 if it is an even number and when the digits are added together the answer is evenly divisible by 3

5 if it ends in a 0 or 5

4 if it ends in 00 or a two digit number that is evenly divisible by 4

3 when the digits are added together and the result is evenly divisible by the number 3

2 if it ends in 0, 2, 4, 6, or 8

Step-by-step explanation:

Depends on what your dividing

its opposite multiplication. So 16 divided 4 is 4 you can figure that out because 4 X 4 is 16. so when doing division you just need to take the smaller number and figure out what multiplied by that can make the largest number
