How to give a better looking output result?

I have got the following output and I would like to get rid of all those high values and obtain a better looking result. FulLSimplify doesn't work for this task. Do you know how to get a better looking output without all those 10^48 etc?

 (6.60881*10^48 beta)/(
 6.97402*10^50 Z0^2 + beta^2 (1.70645*10^47 - 8.3024*10^46 Z0^2))

For instance, I would like Z0 to appear only once.

Answer

A simple workaround:

exp=(6.60881*10^48 beta)/(6.97402*10^50 Z0^2 + beta^2 (1.70645*10^47 - 8.3024*10^46 Z0^2));

(Numerator[exp]/exp[[1]])/Collect[Simplify[Denominator[exp]/exp[[1]]], Z0]
(* (1. beta)/(0.0258208 beta^2 + (105.526 - 0.0125626 beta^2) Z0^2) *)
