We're dividing 770871 by 81 
We're looking to find how many times 81 goes into 770871.

Advancing to step 1:
7 divided by 81 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 81

Let's proceed to step 2:
77 divided by 81 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 81

On to step 3:
81 can be fit into 770 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 729 from 770 to get 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 81

Advancing to step 4:
81 can be fit into 418 5 times, resulting in a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtract 405 from 418 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 81

Advancing to step 5:
When dividing 137 by 81, we get 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 951.0
The remainder is 56 after subtracting 81 from 137.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 81

Let's proceed to step 6:
When dividing 561 by 81, we get 6 with a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 9516.0
Subtracting 486 from 561 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
If we divide 750 by 81, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 9516.9
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
The number 81 fits into 210 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 9516.92
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
480 divided by 81 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 9516.925
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 9516.9259
Subtracting 729 from 750 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
210 divided by 81 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 9516.92592
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 81, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 9516.925925
The remainder is 75 after subtracting 405 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
When dividing 750 by 81, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9516.9259259
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
210 divided by 81 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 9516.92592592
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 9516.92592592 and a remainder of 4.8e-08.
