I have a raster ranging from 0 to 80,000. I want to invert this, such that 80000 becomes 0.0000125.

When I use a raster calculator as (1/x) it returns 1s where the were values and blank where there was a zero. While for zero its correct the other values are wrong.

I tried this option Here 1.0 - (float(x) / 80000.), all the values are converted well only that they are scaled. I dont want this scaling, I need the exact inverses how do i go about this?

    Is your raster a floating raster?

Your raster needs to be "a floating raster" to store decimal values. Transform your integer raster into a floating one, then run the raster calculator again.
