We're dividing 77716 by 81 
Let's see how many times 81 fits into 77716.

On to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

Step 2:
81 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 81

Step 3:
The number 81 fits into 777 9 times, leaving a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 729 from 777 and we're left with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 81

Let's proceed to step 4:
481 divided by 81 is 5 with a remainder of 76.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtracting 405 from 481 leaves us with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 81

On to step 5:
When dividing 766 by 81, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 959.0
Deduct 729 from 766 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 6:
If we divide 370 by 81, we get 4 and a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 959.4
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
460 divided by 81 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 959.45
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
When dividing 550 by 81, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 959.456
If we subtract 486 from 550, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
81 can be fit into 640 7 times, resulting in a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 959.4567
If we take 567 away from 640, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 10:
81 can be fit into 730 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 959.45679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
10 divided by 81 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 959.45679
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 81, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 959.4567901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 959.45679012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 959.45679012, with a leftover of 2.8e-08.
