Let's divide 850686 by 12
Let's see how many times 12 fits into 850686.

Step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

Going ahead to step 2:
85 divided by 12 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 84 from 85 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

On to step 3:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 70.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 12

Advancing to step 4:
When dividing 106 by 12, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 708.0
Subtract 96 from 106 to get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

Going ahead to step 5:
108 divided by 12 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 7089.0
Subtracting 108 from 108 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 12

Let's proceed to step 6:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 70890.0
Subtracting 0 from 6 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.

On to step 7:
If we divide 60 by 12, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 70890.5
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:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 70890.5
Subtracting 0 from 0 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.

Going ahead 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: 70890.5
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 70890.5 with a balance of 0.0.
