How many times does 6 go into 18? The answer is 3 since 3*6 = 18. So 30*6 = 180. This means the number 6 goes into 185 a total of 30 times to have 5 left over.
Another way to think of it: If you had 185 cookies and 6 friends, then each friend gets 30 cookies. They will eat 30*6 = 180 cookies overall and there will be 185-180 = 5 left over.
