Recursion with random

I have a question regarding recursion. I have been learning python by myself and recursion is one of the more difficult ones to wrap my head around. In the question, we are given a piece of weight 2.0. When the piece is =< 0.1, we return 1 piece. Otherwise, recursively break the piece into 2, 3, or 4 random pieces. If those pieces are still not less than 0.1 (or equal) then it breaks again into 2, 3, or 4 random pieces. So far my code looks like this.

import random as rand

def breaker_function(weight_of_piece):
    if weight_of_piece <= 0.1:
        return 1 #returns one piece
    else:
        return breaker_function(weight_of_piece/rand.randint(2,4))

However, this code does not work. I ran it through the debugger and when it reached the recursive step, it broke it into random peice (which were not less than 0.1) and since they were not less than 0.1, the function stopped. And just to clarify, I am not getting an error.

I have also tried double recursion(?) such like:

...

return breaker_function(breaker_function(weight_of_piece/rand.randint(2,4)))

I have also tried to store the random pieces in a list but that just complicated things more so.

But still similar thing happened. I would greatly appreciate your help. Thanks.

Also; in the end, for a piece of size 1.0 i should get approximately 18 ish piece
