Arduino division problems

Hi guys!

I need to use an Arduino to do some simple arithmetics, but it's not that simple

As an example, if I want to divide an integer with an exponent, the Arduino does not seem
to like it: 245/10^-3

I take it that this is due to one number being an integer and the other being a float? The division should
return 245000 (2.45*10^5), but how do I do this in C++/Arduino? The numerator will always be an integer,
and the denominator will always be a float in scientific notation.

Thanks...
