We're dividing 830120 by 12 
We're looking to find how many times 12 goes into 830120.

Advancing to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 12

Advancing to step 2:
12 can be fit into 83 6 times, resulting in a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 72 from 83 and we're left with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

Let's proceed to step 3:
12 goes into 110 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 108 from 110 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 12

Going ahead to step 4:
12 goes into 21 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 691.0
Subtract 12 from 21 to get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 12

Step 5:
12 goes into 92 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 6917.0
If we subtract 84 from 92, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 12

Moving on to step 6:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 69176.0
Subtracting 72 from 80 leaves us 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.

On to step 7:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 69176.6
The remainder is 8 after subtracting 72 from 80.
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 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 69176.66
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.

After the division, we end up with 69176.66 and a remainder of 0.008.
