A good answer might be:

Since 54 = 16 × 3 with a remainder of 6:

digit[ 0 ] = 54 mod 16 = 6,

number = 54 div 16 = 3

Hex Digits from Right to Left

Algorithm: Convert a number
from base 10 to base B repn
place  = 0;
number = number to be converted
         
while (number > 0 )
{
  digit[place] = number mod B ; 
  number       = number div B ;
  place        = place + 1 ;
}            

The first execution of the loop body calculates the digit for place 0, the rightmost digit. Notice what has happened: the first execution says that:

5410   =   3 × 161 + 6 × 160

The first execution of the loop body calculates the digit for place 0, the rightmost digit. The next execution yields the digit for place 1. This calculates digit[1] = 6 mod 16 = 6 and number = 3 div 16 = 0. After this the algorithm is done, and the result is 5410   =   0x36


If you are enthused about this (could happen) you might wish to use mathematical induction to prove that the algorithm is correct. A normal person would just prefer another example.
