845900 ÷ 81 
Let's see how many times 81 fits into 845900.

Let's proceed to step 1:
8 divided by 81 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 81

Moving on to step 2:
The number 81 fits into 84 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 81 from 84 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 81

Going ahead to step 3:
81 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 81

On to step 4:
When dividing 359 by 81, we get 4 with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 324 from 359 and we're left with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 81

Going ahead to step 5:
81 goes into 350 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1044.0
Subtract 324 from 350 to get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 81

Advancing to step 6:
260 divided by 81 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 10443.0
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.

Moving on to step 7:
81 goes into 170 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 10443.2
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
81 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 10443.2
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.

Step 9:
The number 81 fits into 800 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 10443.209
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.

Advancing to step 10:
710 divided by 81 is 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 10443.2098
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
81 goes into 620 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 10443.20987
Deduct 567 from 620 and we're left 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.

Step 12:
530 divided by 81 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 10443.209876
If we subtract 486 from 530, we 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.

Let's proceed to step 13:
When dividing 440 by 81, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10443.2098765
Deduct 405 from 440 and we're left 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.

Moving on to step 14:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 10443.20987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 10443.20987654 with a balance of 2.6e-08.
