Try this please.

$${\frac{{\mathtt{228}}}{{\mathtt{337}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\mathtt{67.655\: \!786\: \!350\: \!148\: \!368}}$$  Multiply the fraction by 100 to get your precentage.

Thanks Radix and Derrickid

Radix: That is a nice interactive web page you have there.  Did you build it yourself ?    

Derrickid: Your answer is good but do not forgetthe % sign.
