Hi,
Try CORDIC algorithm.
Otherwise use look up tabe.
U can also try to implement partially in cordic and partially LUT.
cordic can be use to improve accuracy,whereas lut for coarse inversion.
LUT can not give highly accurate result.for eg 1/7, how to have a such 
abig memory ?
Division method will take longer time.
