We're dividing 863682 by 12 
We want to divide 863682 by 12.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 12

Let's proceed to step 2:
The number 12 fits into 86 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 84 from 86 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 12

On to step 3:
If we divide 23 by 12, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 12 from 23, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 12

Moving on to step 4:
116 divided by 12 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 719.0
If we take 108 away from 116, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 12

Advancing to step 5:
12 can be fit into 88 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7197.0
If we subtract 84 from 88, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

Going ahead to step 6:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 71973.0
Deduct 36 from 42 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.

Going ahead 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: 71973.5
Subtracting 60 from 60 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.

Advancing to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 71973.5
If we subtract 0 from 0, 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 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 71973.5
If we subtract 0 from 0, 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.

After the division, we end up with 71973.5 and a remainder of 0.0.
