Monkeys Dividing the Coconut Pile

Three monkeys spend a day gathering coconuts together. When they have
finished, they are very tired and fall asleep. 

The following morning the first monkey wakes up. Not wishing to disturb
his friends, he decides to divide the coconuts into 3 equal piles, but
there is one left over, so he throws this odd one away, helps himself
to his share, and goes home. 

A few minutes later the second monkey awakes. Not realizing that the
first has already gone, he too divides the coconuts into 3 equal heaps,
finds one left over, throws the odd one away, helps himself to his fair
share, and goes home. 

Then the third monkey does exactly the same. 

What is the smallest possible number of coconuts left?"
