If you have a few different numbers that you are using, divide them each by 8 and if you get a whole number, that number is divisible. If you are trying to figure out what is divisible by 8, you can use a divisibility test.
A number is divisible by 8 if:
the number formed by the last three digits is divisible by 8.
So, an example of this would be:
7, 120.
This number is divisible by 8 because 120 (the last 3 digits) is divisible by 8!

If the last 3 digits are divisible by 8, the number is divisible by 8.
152 is divisible by 8, and the answer is 19.
Not always for example, 36 is not divisible by 8 but it is divisible by 2 and 4.
In a calculater or by hand do 295/8 OR by using the divisibility rule of 8 if the last 3 digits are divisible by 8, so is the entire number. So you would still do 295/8 but now you know why.
If the number formed by the last three digits is divisible by 8. Alternatively, if the number is divisible by 2, the quotient is divisible by 2 and that quotient is divisible by 2.
