If at the end you have a remainder, the number is not evenly divisible by three. If there is no remainder the entire number is divisible by three.In your example 642, I threw away the 6 leaving 4 and 2 , added those = 6 which is divisible by three (actually I remembered that 42 was divisible by 6 so I knew right after I had taken away the first 6 that your number was divisible by 3.
