991474 ÷ 80 
Our goal is to divide 991474 by 80.

Moving on to step 1:
9 divided by 80 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 80

On to step 2:
80 goes into 99 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 80 from 99, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 80

Moving on to step 3:
191 divided by 80 is 2 with a remainder of 31.
The next digit of our result is 2. 
Result so far: 12.0
If we take 160 away from 191, we end up with 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 80

On to step 4:
When dividing 314 by 80, we get 3 with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtract 240 from 314 to get 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 80

Moving on to step 5:
When dividing 747 by 80, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1239.0
If we subtract 720 from 747, we get 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 80

Let's proceed to step 6:
The number 80 fits into 274 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 12393.0
If we take 240 away from 274, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
When dividing 340 by 80, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 12393.4
If we take 320 away from 340, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 12393.42
The remainder is 40 after subtracting 160 from 200.
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:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12393.425
Subtracting 400 from 400 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.

On to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12393.425
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.

Step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12393.425
Subtract 0 from 0 to 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.

The quotient of the division is 12393.425, and the remainder is 0.0.
