Python base conversion algorithm not working?

I'm trying to write a Python script that converts arbitrarily large numbers to binary representation. For some reason, this returns a long series of zeroes until the last few digits. Why?

input = 237481829347283491234198027358096491872350934781238471203874128039741298374109837410983741902374921793047102934710923741902374

while(input > 0):
        print(input % 2)
        input = int(input / 2)

You have exceeded the number of digits that can be held by a float. It's not obvious that you have a float but you do, it's generated by the division operator /. Use the integer division // instead.

input = input // 2

After you've fixed that, be aware that this algorithm puts out the digits in reverse order.
