862075 ÷ 81 
We want to divide 862075 by 81.

Let's proceed to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 81

Let's proceed to step 2:
81 goes into 86 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 81 from 86 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 81

Moving on to step 3:
81 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 81

Advancing to step 4:
When dividing 520 by 81, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 486 from 520 leaves us with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 81

On to step 5:
The number 81 fits into 347 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 1064.0
Subtract 324 from 347 to get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 81

On to step 6:
If we divide 235 by 81, we get 2 and a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 10642.0
If we take 162 away from 235, we end up with 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 7:
81 goes into 730 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 10642.9
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.

Moving on to step 8:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10642.9
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.

Advancing to step 9:
100 divided by 81 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 10642.901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 10642.9012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
If we divide 280 by 81, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 10642.90123
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 10642.901234
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.

Advancing to step 13:
The number 81 fits into 460 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 10642.9012345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
When dividing 550 by 81, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 10642.90123456
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 10642.90123456, with a leftover of 6.4e-08.
