A number which is small than 255 is stored in 20H.

How to display the number by four 7-digits LED display? I use the "scanning" method(4 digits display one by one), so if a number, say 248, have to be transform into "2", "4", "8".

I'm now using this method:
1. Divide the 248 by 100, obtained "2";
2. Multiple the "2" by 100, obtained "200";
3. 248-200=48;
4. 4810=4;
5. 4x10=40;
6. 48-40=8;

Are there any instructions/tricks to transform a number to digits? I program in assembler.
