Oh, dude, let me do some quick math for you. So, like, 16 can go into 43 two times with a remainder of 11. It's like when you try to fit into those skinny jeans after a big meal - you can squeeze in a couple of times, but eventually, you gotta let it go.
Once
43/19 = 2 remainder 5
Not evenly. 16 goes into 690 43 times with a remainder of 0.125
35/43 = 0.814.
43 times
2.279 times.
Ten times.
14.3333 times.
5.86 times
43 times.
Exactly 43 times
3 complete times, and 13/43 of another time.
