875804 ÷ 81 
We want to figure out the number of times 875804 can be divided by 81.

Advancing to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 81

Moving on to step 2:
81 can be fit into 87 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 81 from 87 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 81

Advancing to step 3:
81 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 65, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 81

Going ahead to step 4:
If we divide 658 by 81, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtracting 648 from 658 leaves us with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 81

Let's proceed to step 5:
If we divide 100 by 81, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1081.0
If we take 81 away from 100, we end up with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 81

On to step 6:
When dividing 194 by 81, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 10812.0
Subtracting 162 from 194 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 10812.3
Subtracting 243 from 320 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 10812.39
Subtracting 729 from 770 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
If we divide 410 by 81, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10812.395
Subtract 405 from 410 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
The number 81 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10812.395
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 81, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 10812.39506
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
81 can be fit into 140 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 10812.395061
Deduct 81 from 140 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 13:
If we divide 590 by 81, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 10812.3950617
Deduct 567 from 590 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
230 divided by 81 is 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 10812.39506172
Deduct 162 from 230 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 10812.39506172 with a balance of 6.8e-08.
