We divide 823669 by 81
Let's see how many times 81 fits into 823669.

Going ahead to step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 81

Advancing to step 2:
81 goes into 82 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 81 away from 82, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 81

Advancing to step 3:
13 divided by 81 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 81

Step 4:
81 can be fit into 136 1 times, resulting in a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 81 from 136 and we're left with 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 81

Let's proceed to step 5:
81 goes into 556 6 times with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 1016.0
If we take 486 away from 556, we end up with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 81

Going ahead to step 6:
If we divide 709 by 81, we get 8 and a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 10168.0
Deduct 648 from 709 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
81 can be fit into 610 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 10168.7
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10168.75
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 81, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 10168.753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
When dividing 70 by 81, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 10168.753
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 10168.75308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
When dividing 520 by 81, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 10168.753086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
81 goes into 340 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 10168.7530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 81, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 10168.75308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

After the division, we end up with 10168.75308641 and a remainder of 7.9e-08.
