Well, honey, 40 goes into 56 one time with a remainder of 16. It's simple math, darling. Just divide 56 by 40 and you'll see that it doesn't fit perfectly, leaving you with that pesky little leftover bit.
Oh, dude, let me break it down for you. So, 40 goes into 56 one time because 40 is smaller than 56. But like, there's still 16 left over because math can be so extra sometimes. So, it's like one whole time with a side of 16 leftovers.
