Without actual division find the remainder when 379843 is divided by 3.

Explanation

We know that if a number is divided by `3`, then remainder is obtained by dividing sum of digits by 3.
Here, sum of digits `(3+7+9+8+4+3)` is `34`.
i.e., `34div3` gives `1` as remainder.
Hence, the remainder will be `1` when `379843` is divided by `3`.
