827868 ÷ 81 
We want to divide 827868 by 81.

Let's proceed to step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 81

Moving on to step 2:
When dividing 82 by 81, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 82, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 81

On to step 3:
81 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 81

Going ahead to step 4:
81 goes into 178 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 16 after subtracting 162 from 178.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 81

Moving on to step 5:
When dividing 166 by 81, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1022.0
If we subtract 162 from 166, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 81

On to step 6:
48 divided by 81 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 10220.0
Deduct 0 from 48 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
If we divide 480 by 81, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 10220.5
Deduct 405 from 480 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 8:
If we divide 750 by 81, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 10220.59
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
81 goes into 210 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 10220.592
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10220.5925
The remainder is 75 after subtracting 405 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
81 goes into 750 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 10220.59259
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
The number 81 fits into 210 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 10220.592592
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
81 goes into 480 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 10220.5925925
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 10220.59259259
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 10220.59259259, with a leftover of 2.1e-08.
