Given your stated goal of converting decimal integers into Roman
numerals,
your goal of dealing with one digit at a time will always lead you
astray.

Why not read the entire set of digits as an integer directly?

Given the number 1994, your result should be MCMXCIV.
You cannot arrive at the correct result simply reading one digit at a
time.
