You could convert to string and process each character to a number.

Or  you could divide by 10,  multiple the remainder by 10.

Then subtract the remainder from the divide result and repeat the above line until a single digit remains.

exactly... or convert it to BCD. many PLCs will have ready instruction for that. TwinCat has it too - lookup DEC_TO_BCD. in BCD each digit is in separate nibble (4 bit block)
