 Specifically, if "n" divides 60k, then the sexagesimal representation of 1/"n" is just that for 60k/"n", shifted by some number of places.For instance, suppose we wish to divide by the regular number 54 = 2133.54 is a divisor of 603, and 603/54 = 4000, so dividing by 54 in sexagesimal can be accomplished by multiplying by 4000 and shifting three places.
