Implement division

Python - 73 chars

Takes comma separated input, eg 740,2

from math import*
x,y=input()
z=int(exp(log(x)-log(y)))
print(z*y+y<=x)+z

JavaScript, 61

A=Array,P=prompt,P((','+A(+P())).split(','+A(+P())).length-1)

This makes a string the length of the dividend ,,,,,, (6) and splits on the divisor ,,, (3), resulting in an array of length 3: ['', '', ''], whose length I then subtract one from. Definitely not the fastest, but hopefully interesting nonetheless!

JavaScript - 36 characters

p=prompt;alert(p()*Math.pow(p(),-1))
