We look at the division of 773509 by 81 
We want to divide 773509 by 81.

On to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

Let's proceed to step 2:
When dividing 77 by 81, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 81

Moving on to step 3:
If we divide 773 by 81, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 729 from 773 leaves us with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 81

Going ahead to step 4:
81 can be fit into 445 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtracting 405 from 445 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 81

Advancing to step 5:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
If we subtract 324 from 400, we get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 81

Moving on to step 6:
The number 81 fits into 769 9 times, leaving a remainder of 40.
The next digit of our result is 9. 
Result so far: 9549.0
The remainder is 40 after subtracting 729 from 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 9549.4
Deduct 324 from 400 and we're left with 76.
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 8:
If we divide 760 by 81, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9549.49
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
If we divide 310 by 81, we get 3 and a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 9549.493
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.

Step 10:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 9549.4938
Deduct 648 from 670 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
If we divide 220 by 81, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 9549.49382
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
580 divided by 81 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 9549.493827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
81 can be fit into 130 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 9549.4938271
Deduct 81 from 130 and we're left 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.

Step 14:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9549.49382716
If we take 486 away from 490, we end up 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.

After the division, we end up with 9549.49382716 and a remainder of 4e-09.
