Only two times. There would be 6 left over and dangling, which would be only enough for 15 to go into 36 another 2/5 of a time, not another whole time.

15 will go into 42 two times with 12 left over.
16/15 = 1.066... ≈ 1.1
5 can go into 75 15 times
203 ÷ 15 = 13 with remainder 8 or 13.5333
1 r 15
The answer is Infinity. Numbers keep going up and up and never stop. Therefore fifteen will keep going into a bigger number each time. HOWEVER, if you meant 'how many numbers go into fifteen' , the answer would be 4. Four numbers (1,3,5 and 15) go into 15.
210 ÷ 14 = 15
