To find out the answer to this question, we can do it one way by subtracting 7 from 48 until we can't subtract 7 anymore without getting a negative number.
48 - 7 = 41
41 - 7 = 34
34 - 7 = 27
27 - 7 = 20
20 - 7 = 13
13 - 7 = 6
Now, we can just count the 7s that we subtracted, and when we do, we can see that there are 6 of them, and then we are left with 6, and since 7 can't be subtracted from 6, that will be our remainder.
7 goes into 48 6 times with a remainder of 6.
Hope that helped! =)
