"Suppose that Ingrid has $63$ chocolates. In every step, she meets two friends and divides her pile three ways between herself and her two friends. She divides the chocolates as evenly as possible, but in the event that the chocolates can not be divided perfectly evenly into three piles, she takes the larger pile for herself. How many steps until she is down to one chocolate?"
My logic :
1) Between which powers of 3 is 63 located
2) Low: $3^3 = 27$
3) High: $3^4 = 81$
So for me, I would pick $27 (3$ steeps$)$ instead of $81 (4$ steeps$)$ because she only has $63$ chocolates. $27$ and the leftover $(63-27)$ is for Ingrid.
However, the answer is $4$, anyone willing to explain me? thank you!

Thank you! What is the pattern between each numbers? 63/3 = 21 ; 21/3 = 7 but after I am confused. Thanks!

@YvesDaoust I think that the closure as a duplicate was corect and fine but the delation is not for an answer with many upvotes and more than 8000 vizualitazions. Let try to undelete that, I've already voted.
