By coincidence, I have to do the exact same thing
to show a quantity (0-255) on a display of 0-99 bars.

unsigned char   cByte;
unsigned int    nPercent;

        nPercent = (((int)cByte)*100)/256;

and the division by 256 is identical to >>8,
or just take the high byte.
        0--> 0,
        255 -> 99.
