I assume the question means that it is nine divides it:
116/9 = 12 8/9
713/9 = 79 2/9
495/9 = 55
640/9 = 71 1/9
360/9 = 40
An easier way to do it would be adding all the digits and see if that divides nine:
1+1+6 = 8, not
7+1+3 = 11, not
4+9+5 = 18, yes
...
I will explain why it works if you are interested.
