Let's divide 800936 by 81
We're looking to find how many times 81 goes into 800936.

Step 1:
81 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 81

Step 2:
80 divided by 81 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 81

Moving on to step 3:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 729 away from 800, we end up with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 81

On to step 4:
81 goes into 719 8 times with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 98.0
The remainder is 71 after subtracting 648 from 719.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 81

Going ahead to step 5:
713 divided by 81 is 8 with a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 988.0
Subtract 648 from 713 to get 65.
Append the next digit (6) from the dividend to 65 and continue with: 656 / 81

Advancing to step 6:
81 can be fit into 656 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 9888.0
The remainder is 8 after subtracting 648 from 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 81, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 9888.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
When dividing 800 by 81, we get 9 with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 9888.09
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
When dividing 710 by 81, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 9888.098
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
81 goes into 620 7 times with a remainder of 53.
The next digit of our result is 7. 
Result so far: 9888.0987
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 9888.09876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
81 goes into 440 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9888.098765
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
When dividing 350 by 81, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 9888.0987654
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
81 goes into 260 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 9888.09876543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 9888.09876543 with a remaining 1.7e-08.
