We look at the division of 809410 by 81 
We want to figure out the number of times 809410 can be divided by 81.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 81

On to step 2:
81 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 81

Let's proceed to step 3:
When dividing 809 by 81, we get 9 with a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 729 from 809, we get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 81

On to step 4:
804 divided by 81 is 9 with a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 729 from 804 to get 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 81

Advancing to step 5:
The number 81 fits into 751 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 999.0
Deduct 729 from 751 and we're left with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 81

Moving on to step 6:
When dividing 220 by 81, we get 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 9992.0
Subtracting 162 from 220 leaves us 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.

Let's proceed to step 7:
If we divide 580 by 81, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9992.7
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
130 divided by 81 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 9992.71
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:
The number 81 fits into 490 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 9992.716
If we take 486 away from 490, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9992.716
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 81, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 9992.71604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
If we divide 760 by 81, we get 9 and a remainder of 31.
The next digit of our result is 9. 
Result so far: 9992.716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 9992.7160493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 14:
If we divide 670 by 81, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 9992.71604938
If we subtract 648 from 670, we 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 quotient of the division is 9992.71604938, and the remainder is 2.2e-08.
