Oh, dude, you're hitting me with some math on a chill day? Alright, let's break it down - 15 goes into 210 exactly 14 times. It's like dividing a Pizza into 15 slices, and you end up with 14 whole slices and a little crust left over. Math can be tasty, man.
To determine how many times 15 goes into 210, you would divide 210 by 15. The result of this division is 14, meaning that 15 goes into 210 14 times without any remainder. In mathematical terms, 210 ÷ 15 = 14.
