Well, isn't that a happy little math question? If we have 9 and we want to see how many times 5 fits into it, we can see that it goes in once with a remainder of 4. Remember, there are no mistakes in math, just happy little accidents!
Oh, dude, that's like basic math. 5 goes into 9 one time with a remainder of 4. So, technically, you can fit 5 into 9 once, but there's a little bit left over. Math, man, it's wild.
