I think you are confusing bases with modular arithmetic.
Bases : 8 (base 10) converted to base 5 gives 13 (the first numbers in base 5 are : 0, 1, 2, 3, 4, 10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31 ...)
Modular arithmetic :

(mod 5) (which means that the remainder of the division of 8 by 5 is 3)
To write out the actual problem, you can either try to use LaTeX symbols (painful to write), or you can open Paint and roughly scribble your problem, then upload and paste the image on a new comment ?
