1533.5952 / 50.42 = 30.41634...
30.41634 x 50 = 1520.81733
I would probably round down a couple of precision points and just use 1520.8 or even 1521.
You can use the same formula for any axis:
((Current number of steps / actual output length) * desired output length) = refined number of steps to insert in to Marlin, Repetier, etc.
