Let's divide 21360791 by 768
We want to divide 21360791 by 768.

Advancing to step 1:
768 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 768

Step 2:
If we divide 21 by 768, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 768

Step 3:
The number 768 fits into 213 0 times, leaving a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Bring next digit (6) of the dividend behind the 213 and repeat the process: 2136 / 768

Going ahead to step 4:
2136 divided by 768 is 2 with a remainder of 600.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 600 after subtracting 1536 from 2136.
Fetch the next digit (0) from the dividend, attach it to 600 and continue: 6000 / 768

Advancing to step 5:
If we divide 6000 by 768, we get 7 and a remainder of 624.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 5376 from 6000, we get 624.
Bring next digit (7) of the dividend behind the 624 and repeat the process: 6247 / 768

Moving on to step 6:
If we divide 6247 by 768, we get 8 and a remainder of 103.
The next digit of our result is 8. 
Result so far: 278.0
If we take 6144 away from 6247, we end up with 103.
Fetch the next digit (9) from the dividend, attach it to 103 and continue: 1039 / 768

Let's proceed to step 7:
When dividing 1039 by 768, we get 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 2781.0
Subtracting 768 from 1039 leaves us with 271.
Take the next digit (1) from the dividend and append it to 271, then repeat: 2711 / 768

Let's proceed to step 8:
The number 768 fits into 2711 3 times, leaving a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 27813.0
Subtract 2304 from 2711 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 9:
When dividing 4070 by 768, we get 5 with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 27813.5
The remainder is 230 after subtracting 3840 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
When dividing 2300 by 768, we get 2 with a remainder of 764.
Write down 2 as next digit of the result. 
Result so far: 27813.52
If we subtract 1536 from 2300, we get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 11:
If we divide 7640 by 768, we get 9 and a remainder of 728.
Record the quotient 9 as the next digit in the result. 
Result so far: 27813.529
Subtract 6912 from 7640 to get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Going ahead to step 12:
When dividing 7280 by 768, we get 9 with a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 27813.5299
The remainder is 368 after subtracting 6912 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

In conclusion, the division gives 27813.5299 with a balance of 0.00368.
