We look at the division of 208686 by 12 
We're looking to find how many times 12 goes into 208686.

Advancing to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Going ahead to step 2:
When dividing 20 by 12, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 12 from 20 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 12

Advancing to step 3:
12 goes into 88 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 84 away from 88, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 12

Step 4:
If we divide 46 by 12, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 173.0
Subtracting 36 from 46 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 12

Going ahead to step 5:
12 can be fit into 108 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 1739.0
The remainder is 0 after subtracting 108 from 108.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 12

Moving on to step 6:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 17390.0
Deduct 0 from 6 and we're left with 6.
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 goes into 60 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 17390.5
Subtract 60 from 60 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.

Going ahead to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17390.5
The remainder is 0 after subtracting 0 from 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 9:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17390.5
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.

The quotient of the division is 17390.5, and the remainder is 0.0.
