816731 ÷ 12 
Our goal is to divide 816731 by 12.

Step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 12

Step 2:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 9 after subtracting 72 from 81.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 12

Let's proceed to step 3:
The number 12 fits into 96 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 96 from 96 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 12

Going ahead to step 4:
If we divide 7 by 12, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 680.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 12

Let's proceed to step 5:
12 can be fit into 73 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6806.0
Subtracting 72 from 73 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 12

Step 6:
If we divide 11 by 12, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 68060.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 68060.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 12 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 68060.91
Subtract 12 from 20 to get 8.
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 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 68060.916
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.

Advancing to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 68060.9166
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.

In conclusion, the division gives 68060.9166 with a balance of 8e-05.
