Let's divide 991686 by 80
Our goal is to divide 991686 by 80.

Advancing to step 1:
9 divided by 80 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 80

Let's proceed to step 2:
80 can be fit into 99 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 80 away from 99, we end up with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 80

Going ahead to step 3:
191 divided by 80 is 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 160 from 191 and we're left with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 80

Let's proceed to step 4:
80 goes into 316 3 times with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 240 from 316 and we're left with 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 80

Going ahead to step 5:
80 can be fit into 768 9 times, resulting in a remainder of 48.
The next digit of our result is 9. 
Result so far: 1239.0
Subtracting 720 from 768 leaves us with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 80

Step 6:
If we divide 486 by 80, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 12396.0
If we take 480 away from 486, we end up 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:
80 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 12396.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
80 goes into 600 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 12396.07
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12396.075
If we take 400 away from 400, we end up 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.

Step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 12396.075
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.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12396.075
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.

The quotient of the division is 12396.075, and the remainder is 0.0.
