873782 divided by 81 
We want to figure out the number of times 873782 can be divided by 81.

Going ahead to step 1:
81 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 81

Step 2:
81 can be fit into 87 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 81 from 87 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 81

Moving on to step 3:
63 divided by 81 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 81

Moving on to step 4:
When dividing 637 by 81, we get 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 567 from 637 to get 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 81

Step 5:
When dividing 708 by 81, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 1078.0
Subtracting 648 from 708 leaves us with 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 81

Advancing to step 6:
When dividing 602 by 81, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 10787.0
If we subtract 567 from 602, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
350 divided by 81 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 10787.4
Subtracting 324 from 350 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 81 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 10787.43
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
81 goes into 170 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 10787.432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
81 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 10787.432
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
If we divide 800 by 81, we get 9 and a remainder of 71.
The next digit of our result is 9. 
Result so far: 10787.43209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 12:
710 divided by 81 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 10787.432098
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
81 goes into 620 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 10787.4320987
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
81 goes into 530 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 10787.43209876
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 10787.43209876 with a remainder of 4.4e-08.
