Let's divide 7805 by 81
Our goal is to divide 7805 by 81.

Step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 81

Advancing to step 2:
The number 81 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 81

Step 3:
81 goes into 780 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 729 from 780 leaves us with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 81

Advancing to step 4:
515 divided by 81 is 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtracting 486 from 515 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 5:
If we divide 290 by 81, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 96.3
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 6:
If we divide 470 by 81, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 96.35
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
650 divided by 81 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 96.358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 96.358
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 96.35802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
81 goes into 380 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 96.358024
Deduct 324 from 380 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
81 can be fit into 560 6 times, resulting in a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 96.3580246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 12:
740 divided by 81 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 96.35802469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 96.35802469 with a remainder of 1.1e-08.
