We're dividing 685729 by 81 
Our goal is to divide 685729 by 81.

Step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 81

Advancing to step 2:
68 divided by 81 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 81

Advancing to step 3:
The number 81 fits into 685 8 times, leaving a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 648 from 685 to get 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 81

On to step 4:
377 divided by 81 is 4 with a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtract 324 from 377 to get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 81

Moving on to step 5:
The number 81 fits into 532 6 times, leaving a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 846.0
The remainder is 46 after subtracting 486 from 532.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 81

On to step 6:
If we divide 469 by 81, we get 5 and a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 8465.0
The remainder is 64 after subtracting 405 from 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
When dividing 640 by 81, we get 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 8465.7
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
81 goes into 730 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8465.79
If we subtract 729 from 730, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 81, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8465.79
Deduct 0 from 10 and we're left with 10.
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:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8465.7901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
If we divide 190 by 81, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 8465.79012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 8465.790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
If we divide 370 by 81, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 8465.7901234
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
460 divided by 81 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 8465.79012345
Subtracting 405 from 460 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 8465.79012345, and the remainder is 5.5e-08.
