We divide 99017186 by 12
Our goal is to divide 99017186 by 12.

Going ahead to step 1:
12 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Going ahead to step 2:
99 divided by 12 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 96 from 99 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Advancing to step 3:
30 divided by 12 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we take 24 away from 30, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

On to step 4:
61 divided by 12 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 825.0
If we subtract 60 from 61, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

Let's proceed to step 5:
17 divided by 12 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 8251.0
Deduct 12 from 17 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

On to step 6:
12 can be fit into 51 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 82514.0
Subtracting 48 from 51 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

Advancing to step 7:
38 divided by 12 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 825143.0
Subtracting 36 from 38 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 12

Going ahead to step 8:
The number 12 fits into 26 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 8251432.0
Subtracting 24 from 26 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.

Let's proceed to step 9:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 8251432.1
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.

Going ahead to step 10:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8251432.16
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.

Advancing to step 11:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 8251432.166
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.

The final outcome is 8251432.166, with a leftover of 0.0008.
