this might be a lengthy question but I would appreciate any help.

the criteria seems simple and I know how to print the ASCII table. Although how would one space 20 characters on a line using modular division?

this is the question:

" Write a program to print out as many characters as possible in the ASCII table. A while(..) Loop must be used for this purpose. Use Modular Division to ensure that 20 characters are printed per row with separation between each character of two white spaces."
