Division with really big numbers

Question

I was just wondering what different strategies there are for division when dealing with big numbers. By big numbers, I mean ~50 digit numbers .

e.g. 9237639100273856744

Answer 1

if you don't need very exact result, you can use logarithms and exponents. Exponent is the function f(x)=e^x, where e is a mathmaticall constant equal to 2.71828182845...
Logarithm (marked by ln) is the inverse of the exponent.

Since ln(a/b)=ln(a)-ln(b), to calculate a/b you need to:
Calculate ln(a) and ln(b) [By library function, logarithm table or other methods]
substruct them: temp=ln(a)-lb(b)
calculate the exponent e^temp
