Well, honey, 79 goes into 640 approximately 8 times with a remainder of 8. So, you can't fit 79 into 640 perfectly, but you can get pretty darn close. Just like trying to squeeze into those jeans after a big meal - almost there, but not quite!
To find out how many times 79 goes into 640, you would perform long division. When you divide 640 by 79, you get 8 with a remainder of 8. Therefore, 79 goes into 640 8 times with a remainder of 8.
