I checked to see if maybe there was just a problem in my code. I used a much higher number as the input, which the program is simply supposed to divide by 52, and this time - using debug - it ran correctly and displayed the correct information, but then when I used the correct input to allow the command prompt to close I got the error again.

Not even an error.
