Let's divide 845855 by 81
We're looking to find how many times 81 goes into 845855.

Going ahead to step 1:
8 divided by 81 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 81

Going ahead to step 2:
The number 81 fits into 84 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 81 from 84 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 81

Let's proceed to step 3:
81 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 35, we end up with 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 81

Going ahead to step 4:
81 can be fit into 358 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we subtract 324 from 358, we get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 81

Step 5:
The number 81 fits into 345 4 times, leaving a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 1044.0
The remainder is 21 after subtracting 324 from 345.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 81

Going ahead to step 6:
81 can be fit into 215 2 times, resulting in a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 10442.0
If we take 162 away from 215, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
If we divide 530 by 81, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 10442.6
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
440 divided by 81 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 10442.65
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
When dividing 350 by 81, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 10442.654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
The number 81 fits into 260 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 10442.6543
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 10442.65432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10442.65432
If we take 0 away from 80, we end up 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.

Advancing to step 13:
800 divided by 81 is 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 10442.6543209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 14:
710 divided by 81 is 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 10442.65432098
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.

The final result is 10442.65432098 with a remainder of 6.2e-08.
