Test if 8 is divisible by all possible numbers. Start by testing the smallest number possible (1) and making your way up to the largest number possible (7).
8/1= 8
8/2=4
8/3= not a whole number
8/4 = 2
8/5 = not a whole number
8/6 = not a whole number
8/7 = not a whole number
note we did not try 8/8 because that would not be considered "taking apart".
After sorting out our test answers we can conclude that you can take 8 apart in three ways. In 8 groups of 1, in 2 groups of 4, and in 4 groups of 2. You can show this in pictures by illustrating these groups. See Below
