Let's divide 493404 by 12
We're looking to find how many times 12 goes into 493404.

On to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 12

Moving on to step 2:
If we divide 49 by 12, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 48 from 49 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 12

Going ahead to step 3:
12 can be fit into 13 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 12

Moving on to step 4:
12 goes into 14 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 411.0
Subtracting 12 from 14 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

On to step 5:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 4111.0
Subtracting 12 from 20 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 12

On to step 6:
84 divided by 12 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 41117.0
If we take 84 away from 84, we end up 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 7:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41117.0
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.

Advancing to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41117.0
Subtract 0 from 0 to get 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 quotient of the division is 41117.0, and the remainder is 0.0.
