We look at the division of 845871 by 81 
Let's see how many times 81 fits into 845871.

Step 1:
81 goes into 8 0 times with 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.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 81

Let's proceed to step 2:
If we divide 84 by 81, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 81 from 84.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 81

On to step 3:
35 divided by 81 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 81

Advancing to step 4:
When dividing 358 by 81, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 34 after subtracting 324 from 358.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 81

Advancing to step 5:
81 goes into 347 4 times with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 1044.0
Subtracting 324 from 347 leaves us with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 81

Let's proceed to step 6:
81 can be fit into 231 2 times, resulting in a remainder of 69.
The next digit of our result is 2. 
Result so far: 10442.0
Subtracting 162 from 231 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
If we divide 690 by 81, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 10442.8
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
When dividing 420 by 81, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10442.85
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 10442.851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
When dividing 690 by 81, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 10442.8518
Deduct 648 from 690 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
When dividing 420 by 81, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 10442.85185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 10442.851851
If we subtract 81 from 150, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
When dividing 690 by 81, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 10442.8518518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
81 goes into 420 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10442.85185185
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 10442.85185185 with a balance of 1.5e-08.
