I definitely agree with Russell here.  This was one of the first things I did on a Pic and I learned much more than if I had copied a routine from somewhere.

A hint is to study the ASCII chart carefully because there are some shortcuts you can take based on how the ASCII codes are arranged.

There are various ways of doing this "properly" or at least 
efficiently BUT I strongly suggest that you try doing it yourself 
first by whatever means you can think of as a learning exercise.

Consider brute force for a start.

If > 9
    subtract and counts 10's until < 10
    report 10s
else
    10's = 0
endif

Remainder = 1s
Report 1's

There are better ways of doing this, but the day you make the above 
work by yourself you will feel very pleased AND have learned several 
useful things.
