Yes. 384 / 3 = 128

The quickest way to identify a number divisible by 3 is that the sum of its digits is a number divisible by 3. Here, 3 + 8 + 4 = 15, which is divisible by 3.

This works for any number, for example:

111111 is divisible by 3 (sums to 6)

1111111 is not divisible by 3 (sums to 7)

but 1221111 is, and so is 1311111 and 1112211 because they all total 9.
