Let's divide 766383 by 81
We want to figure out the number of times 766383 can be divided by 81.

On to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 81

On to step 2:
81 can be fit into 76 0 times, resulting in a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 81

Advancing to step 3:
The number 81 fits into 766 9 times, leaving a remainder of 37.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 729 from 766 and we're left with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 81

Let's proceed to step 4:
If we divide 373 by 81, we get 4 and a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
The remainder is 49 after subtracting 324 from 373.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 81

Advancing to step 5:
498 divided by 81 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 946.0
Deduct 486 from 498 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 81

Advancing to step 6:
The number 81 fits into 123 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 9461.0
The remainder is 42 after subtracting 81 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
420 divided by 81 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9461.5
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
81 can be fit into 150 1 times, resulting in a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 9461.51
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
When dividing 690 by 81, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 9461.518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 81 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 9461.5185
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 9461.51851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
690 divided by 81 is 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 9461.518518
Deduct 648 from 690 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
81 goes into 420 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9461.5185185
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 9461.51851851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 9461.51851851 and a remainder of 6.9e-08.
