We divide 991868 by 12
We want to figure out the number of times 991868 can be divided by 12.

Moving on to step 1:
9 divided by 12 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Going ahead to step 2:
If we divide 99 by 12, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
If we take 96 away from 99, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 12

Moving on to step 3:
12 can be fit into 31 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 82.0
Subtract 24 from 31 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

Let's proceed to step 4:
12 can be fit into 78 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 826.0
If we take 72 away from 78, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Step 5:
If we divide 66 by 12, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 8265.0
If we take 60 away from 66, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 12

Step 6:
When dividing 68 by 12, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 82655.0
If we take 60 away from 68, we end up 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.

Moving on to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 82655.6
Subtract 72 from 80 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 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 82655.66
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.

The final result is 82655.66 with a remainder of 0.008.
