How many times can 2 goes into 78 and leave a remainder
2 can actually go into 78 with no remainder. 78/2 is 39. Here is a trick: look at the last digit of the number. If it is even, it can be divided by 2!
2 goes into 78 evenly, 39 times, with no remainder.
If it's a remainder you want, then you must do it only 38 times.
That will give you a remainder of 2 , but on a test, this answer
will be marked wrong.
