Hello There @Diamondinthesky123 (Cute Username)
When you state the question, "How many times does 2 go into 19", I assume your talking about Long Division. (Not so long in this case)
In this case, we would divide 19 by 2, resulting in 9 with a remainder of 1.
Thats It! :)
I hope I helped, Have a great Day!
Thank you,
