For division, we have subtraction by a different name: For 6/2, we subtract 2 from 6, take the reduced value and repeat UNTIL we either reach 0 or there's not enough remaining; count the number of iterations:
6 - 2 = 4
4 - 2 = 2
2 - 2 = 0
3 times we subtracted 2: 6/2 = 3
Now, do the same for 3/0:
3 - 0 = 3
3 - 0 = 3 ...
Infinite iterations.
There's that pesky infinity, again. (Not whistling Dixie.)
You think you reach 0 after subtracting 0 from 6 an infinite number of times?
How precious.
Do you want to reconsider...when you've sobered up?
No need to reconsider.
You're counting interations taken to reach zero.
In your first example you come up with the (correct) count of 3 iterations to reach zero.
In your second example you come up with the (incorrect) count of infinity iterations to reach zero.
The fact that "infinity" is a braindead answer to the second part is not my problem.
