We look at the division of 80912174 by 80 
We're looking to find how many times 80 goes into 80912174.

Let's proceed to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 80

Let's proceed to step 2:
80 goes into 80 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 80 from 80, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 80

Step 3:
If we divide 9 by 80, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 80

Step 4:
80 goes into 91 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtract 80 from 91 to get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 80

Going ahead to step 5:
The number 80 fits into 112 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1011.0
The remainder is 32 after subtracting 80 from 112.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 80

Going ahead to step 6:
When dividing 321 by 80, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 10114.0
If we subtract 320 from 321, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 80

Moving on to step 7:
80 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 101140.0
If we take 0 away from 17, we end up with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 80

Advancing to step 8:
174 divided by 80 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1011402.0
If we take 160 away from 174, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
80 can be fit into 140 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1011402.1
If we take 80 away from 140, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 80, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1011402.17
If we take 560 away from 600, we end up 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.

Moving on to step 11:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1011402.175
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 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1011402.175
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.

Going ahead to step 13:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1011402.175
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.

The quotient of the division is 1011402.175, and the remainder is 0.0.
