That means the number itself is divisible by three. the sum of the digits in 144, for example, is 9. 144 divided by 3 is 48. The sum of the digits in 21 is 3. 21 divided by 3 is 7.If the number is an even number and the sum of the digits is divisible by 3, the number is also divisible by 6. 144 is even and the sum of the digits is divisible by 3, so 144 is also divisible by 6. 144/6 = 24. And finally, if the sum is divisible by 9, the number itself is also divisible by 9. 27 is an example of this.

9046. 20 ÷ 11 = 1.81... With the 81 repeating forever. So the sum of the first 2011 digits is the first digit plus the next 2010 digits which are "81" repeated 1005 times. Sum = 1 + (8 + 1) x 1005 = 9046
