Let's divide 493419 by 3
We want to divide 493419 by 3.

On to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Moving on to step 2:
If we divide 19 by 3, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 18 from 19, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Going ahead to step 3:
If we divide 13 by 3, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Going ahead to step 4:
3 goes into 14 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1644.0
If we take 12 away from 14, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Going ahead to step 5:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 16447.0
The remainder is 0 after subtracting 21 from 21.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Advancing to step 6:
If we divide 9 by 3, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 164473.0
Deduct 9 from 9 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 164473.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 164473.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 164473.0 with a remainder of 0.0.
