863922 divided by 12 
Let's see how many times 12 fits into 863922.

Going ahead to step 1:
12 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

On to step 2:
12 can be fit into 86 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Let's proceed to step 3:
The number 12 fits into 23 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 12 from 23, we get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 12

Going ahead to step 4:
12 goes into 119 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 719.0
Subtracting 108 from 119 leaves us with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 12

Moving on to step 5:
112 divided by 12 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 7199.0
Deduct 108 from 112 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Moving on to step 6:
If we divide 42 by 12, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 71993.0
Subtracting 36 from 42 leaves us 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:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 71993.5
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.

Going ahead to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 71993.5
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 next digit of our result is 0. 
Result so far: 71993.5
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.

The quotient of the division is 71993.5, and the remainder is 0.0.
