768993 divided by 81 
We want to figure out the number of times 768993 can be divided by 81.

On to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 81

Step 2:
81 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (8) from the dividend and append it to 76, then repeat: 768 / 81

Going ahead to step 3:
81 can be fit into 768 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 729 from 768 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 81

Advancing to step 4:
399 divided by 81 is 4 with a remainder of 75.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtract 324 from 399 to get 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 81

On to step 5:
759 divided by 81 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 949.0
Deduct 729 from 759 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 81

Advancing to step 6:
81 goes into 303 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 9493.0
Subtracting 243 from 303 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 81, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 9493.7
Deduct 567 from 600 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
The number 81 fits into 330 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 9493.74
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9493.74
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
600 divided by 81 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 9493.7407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
330 divided by 81 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 9493.74074
Subtract 324 from 330 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 9493.74074
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
If we divide 600 by 81, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 9493.7407407
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 14:
If we divide 330 by 81, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 9493.74074074
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 9493.74074074 with a balance of 6e-09.
