We divide 490680 by 12
Let's see how many times 12 fits into 490680.

Going ahead to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Let's proceed 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
The remainder is 1 after subtracting 48 from 49.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

On to step 3:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 10, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 12

Advancing to step 4:
12 can be fit into 106 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 408.0
If we subtract 96 from 106, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 12

On to step 5:
When dividing 108 by 12, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4089.0
Subtract 108 from 108 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Step 6:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40890.0
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.

Moving on to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 40890.0
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.

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: 40890.0
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.

After the division, we end up with 40890.0 and a remainder of 0.0.
