I'm writing a bit of code in PyCharm, and I want the division to be much more accurate than it currently is (40-50 numbers instead of about 15). How Can I accomplish this?

Thanks.

Check out the decimal module:

>>> from decimal import *
>>> getcontext().prec = 50
>>> Decimal(1)/Decimal(7)
Decimal('0.14285714285714285714285714285714285714285714285714')

If you're interested in more sophisticated operations than decimal provides, you can also look at libraries like bigfloat, or mpmath (which I use, and like a lot.)
