Python isn't displaying recurring decimals correctly?

I wanted python to display recurring decimals, so I tried the normal division code, but that only displayed about 10 digits. I wanted more, so I tried using the decimal module and this was the code:

from decimal import *
def divide(x,y)
      return(x/y)
print(Decimal(divide(10,3)))
input()

This gave more digits, but for some reason the decimals are wrong. This is what was displayed:

3.333333333333333481363069950020872056484222412109375

It stops recurring after a while and I have no idea why. Is Python unable to produce a large number of recurring decimals, or is something wrong with my code?

Have a look at fixed point decimals: https://stackoverflow.com/questions/45136821/how-to-convert-float-to-fixed-point-decimal-in-python – user_na May 22 '21 at 13:21
You passed a `float` to your `Decimal`, don't do that. Use a string – juanpa.arrivillaga May 24 '21 at 01:15
So do something like `print(divide(Decimal(10), Decimal(3)))` if you want to input a decimal number, use a string, not a float – juanpa.arrivillaga May 24 '21 at 01:17
