872104 ÷ 81 
We want to divide 872104 by 81.

Going ahead to step 1:
81 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 81

Moving on to step 2:
87 divided by 81 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 81 from 87 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 81

Step 3:
62 divided by 81 is 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 81

Moving on to step 4:
81 goes into 621 7 times with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtracting 567 from 621 leaves us with 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 81

Going ahead to step 5:
81 goes into 540 6 times with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 1076.0
Subtracting 486 from 540 leaves us with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 81

Advancing to step 6:
81 goes into 544 6 times with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 10766.0
If we take 486 away from 544, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 10766.7
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
81 can be fit into 130 1 times, resulting in a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 10766.71
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
81 can be fit into 490 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 10766.716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
81 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10766.716
Deduct 0 from 40 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.

Step 11:
400 divided by 81 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 10766.71604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
81 can be fit into 760 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 10766.716049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
If we divide 310 by 81, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 10766.7160493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 14:
When dividing 670 by 81, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 10766.71604938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 10766.71604938, with a leftover of 2.2e-08.
