Take logarithm, process the data, and finally take antilog.

Alternatively you can convert the numbers in binary system and later convert them to decimal system.

how to normalize a set of numbers

Scaling from 0-255 is the same as scaling from 0-1, then multiplying by 255.
jiveshgovil has hit on something ...
If the data are to be displayed (presuming 0-255 might be pixel values or such), you might want to scale a function of the data rather than the data themselves, in order to spread the values more uniformly (as in contrast enhancement and such).
