A witch gives you a bag of n marbles. One of them is lucky. If you touch it, you will shit gold.
So you divide the marbles into m equal-ish piles, differing by no more than 1 in size, and give each to a friend.
Then, each of your friends divides their pile into m equal-ish piles and gives each of these to a friend.
This continues until nobody has more than one marble.
