Let's divide 855463 by 81
We're looking to find how many times 81 goes into 855463.

Moving on to step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 81

Advancing to step 2:
The number 81 fits into 85 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 81 from 85, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 81

Advancing to step 3:
81 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 45 to get 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 81

Moving on to step 4:
The number 81 fits into 454 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 105.0
If we subtract 405 from 454, we get 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 81

Step 5:
If we divide 496 by 81, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
If we take 486 away from 496, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 81

Step 6:
81 goes into 103 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 10561.0
The remainder is 22 after subtracting 81 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 10561.2
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
The number 81 fits into 580 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 10561.27
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
81 goes into 130 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 10561.271
If we take 81 away from 130, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
81 can be fit into 490 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10561.2716
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
81 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10561.2716
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 81, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 10561.271604
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 10561.2716049
Deduct 729 from 760 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
When dividing 310 by 81, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 10561.27160493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 10561.27160493 and a remainder of 6.7e-08.
