We look at the division of 490808 by 12 
Let's see how many times 12 fits into 490808.

Step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 12

Advancing to step 2:
If we divide 49 by 12, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 48 from 49 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Going ahead to step 3:
When dividing 10 by 12, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 12

Let's proceed to step 4:
12 goes into 108 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 409.0
The remainder is 0 after subtracting 108 from 108.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 12

Let's proceed to step 5:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4090.0
If we subtract 0 from 0, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 12

Let's proceed to step 6:
12 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 40900.0
If we subtract 0 from 8, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 40900.6
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 40900.66
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 40900.66, and the remainder is 0.008.
