We're dividing 691231 by 81 
We want to figure out the number of times 691231 can be divided by 81.

Going ahead to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 81

Let's proceed to step 2:
If we divide 69 by 81, we get 0 and a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 81

Let's proceed to step 3:
The number 81 fits into 691 8 times, leaving a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 648 from 691 leaves us with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 81

Step 4:
If we divide 432 by 81, we get 5 and a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 27 after subtracting 405 from 432.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 81

Advancing to step 5:
If we divide 273 by 81, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 853.0
If we subtract 243 from 273, we get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 81

Advancing to step 6:
If we divide 301 by 81, we get 3 and a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 8533.0
Deduct 243 from 301 and we're left 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.

On to step 7:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 8533.7
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.

Moving on to step 8:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 8533.71
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
81 goes into 490 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8533.716
Deduct 486 from 490 and we're left 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.

Moving on 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: 8533.716
If we take 0 away from 40, we end up 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.

Moving on to step 11:
81 goes into 400 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8533.71604
Subtract 324 from 400 to 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.

On to step 12:
81 can be fit into 760 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 8533.716049
Subtract 729 from 760 to get 31.
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.
The next digit of our result is 3. 
Result so far: 8533.7160493
Subtracting 243 from 310 leaves us 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.

Let's proceed to step 14:
81 goes into 670 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8533.71604938
Deduct 648 from 670 and we're left with 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 8533.71604938, and the remainder is 2.2e-08.
