81194977 ÷ 80 
Our goal is to divide 81194977 by 80.

On to step 1:
8 divided by 80 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 80

Step 2:
When dividing 81 by 80, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 81 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 80

On to step 3:
If we divide 11 by 80, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 80

Going ahead to step 4:
When dividing 119 by 80, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 101.0
Deduct 80 from 119 and we're left with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 80

Let's proceed to step 5:
394 divided by 80 is 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 1014.0
Subtracting 320 from 394 leaves us with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 80

Going ahead to step 6:
749 divided by 80 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 10149.0
If we subtract 720 from 749, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 80

On to step 7:
When dividing 297 by 80, we get 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 101493.0
The remainder is 57 after subtracting 240 from 297.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 80

Moving on to step 8:
80 can be fit into 577 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 1014937.0
The remainder is 17 after subtracting 560 from 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
80 can be fit into 170 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 1014937.2
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
100 divided by 80 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1014937.21
Subtracting 80 from 100 leaves us 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.

Let's proceed to step 11:
200 divided by 80 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1014937.212
Subtracting 160 from 200 leaves us 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.

Advancing to step 12:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1014937.2125
Deduct 400 from 400 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.

Going ahead to step 13:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1014937.2125
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.

Step 14:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1014937.2125
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.

The final outcome is 1014937.2125, with a leftover of 0.0.
