16-bit floating point division (half-precision, excluding edge cases, just positive normal numbers)?

Question

I tried to divide just a normal positive 16-bit-float-point number by a normal positive 16-bit-float-point number (half-precision, excluding edge cases). I did the sign with XOR gate, the exponent with 5-bit subtractor, but couldn't do the mantissa. How can I do the normalizing and rounding in Logisim?
