We're dividing 980490 by 12 
We want to divide 980490 by 12.

On to step 1:
12 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

Step 2:
98 divided by 12 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 96 from 98, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 12

Going ahead to step 3:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 12 away from 20, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 12

On to step 4:
If we divide 84 by 12, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 817.0
If we take 84 away from 84, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

Step 5:
If we divide 9 by 12, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 8170.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Let's proceed to step 6:
90 divided by 12 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 81707.0
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 81707.5
If we subtract 60 from 60, we 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.

Moving on to step 8:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81707.5
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.

Going ahead to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81707.5
If we take 0 away from 0, 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.

In conclusion, the division gives 81707.5 with a balance of 0.0.
