Way before calculators my Great Grandmother taught me how to do long hand cube root or square roots. Say you were to determine the cube root of 46656. You start by dividing by 2 if possible, and continue, then 3, then 4 etc.
2(46656)
2(23328)
2(11664)
2(5832)
2(2916)
2(1458)
3(729)
3(243)
3(81)
3(9)
3(3)
3(1)
Then for cube root groups of 3 roots or 2 X 2 X 3 X 3 = 36
QED
