Thanks to you and Eike, Steven, I was able to write this little
function that does the job for me, and more:

>>> def divide_large_ints(n, div):
	    x = divmod(n, div)
	    return str(x[0]) + str(x[1]/div).lstrip('0')

	
>>> n = 2000000000000000000000000000000033
>>> div = 2
>>> divide_large_ints(n, div)
'1000000000000000000000000000000016.5'
>>>
