I am stuck on this and need some help. I am having difficulty breaking up the large number into something that I can use. I took my assignment from 4a and converted it to work with numbers up to 999, and made that into a method that I can call. What I need to figure out is the best way to break up the number 999,999,999,999 into 3 digit pieces. I don't know if I should use sub-strings and then parse the integers from those strings or use some math to divide this number up. Any help or insight would be greatly appreciated. Thanks
