Let's divide 21459109 by 792
Our goal is to divide 21459109 by 792.

Going ahead to step 1:
2 divided by 792 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 792

On to step 2:
792 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 792

Going ahead to step 3:
792 goes into 214 0 times with a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 792

Going ahead to step 4:
When dividing 2145 by 792, we get 2 with a remainder of 561.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1584 from 2145 and we're left with 561.
Take the next digit (9) from the dividend and append it to 561, then repeat: 5619 / 792

Going ahead to step 5:
792 goes into 5619 7 times with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 5544 from 5619 to get 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 792

Going ahead to step 6:
792 goes into 751 0 times with a remainder of 751.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Subtracting 0 from 751 leaves us with 751.
Append the next digit (0) from the dividend to 751 and continue with: 7510 / 792

Step 7:
The number 792 fits into 7510 9 times, leaving a remainder of 382.
Use 9 as the next digit of our solution. 
Result so far: 2709.0
Deduct 7128 from 7510 and we're left with 382.
Fetch the next digit (9) from the dividend, attach it to 382 and continue: 3829 / 792

Step 8:
792 goes into 3829 4 times with a remainder of 661.
Put 4 as the next digit of the answer. 
Result so far: 27094.0
Deduct 3168 from 3829 and we're left with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Going ahead to step 9:
792 goes into 6610 8 times with a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 27094.8
If we subtract 6336 from 6610, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 10:
If we divide 2740 by 792, we get 3 and a remainder of 364.
The next digit of our result is 3. 
Result so far: 27094.83
Deduct 2376 from 2740 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
792 can be fit into 3640 4 times, resulting in a remainder of 472.
Use 4 as the next digit of our solution. 
Result so far: 27094.834
Subtracting 3168 from 3640 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 12:
792 goes into 4720 5 times with a remainder of 760.
Put 5 as the next digit of the answer. 
Result so far: 27094.8345
If we take 3960 away from 4720, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 13:
The number 792 fits into 7600 9 times, leaving a remainder of 472.
The next digit of our result is 9. 
Result so far: 27094.83459
The remainder is 472 after subtracting 7128 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 14:
4720 divided by 792 is 5 with a remainder of 760.
The number 5 becomes the next digit in our result. 
Result so far: 27094.834595
The remainder is 760 after subtracting 3960 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 15:
If we divide 7600 by 792, we get 9 and a remainder of 472.
Write down 9 as next digit of the result. 
Result so far: 27094.8345959
Subtract 7128 from 7600 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 16:
When dividing 4720 by 792, we get 5 with a remainder of 760.
The number 5 becomes the next digit in our result. 
Result so far: 27094.83459595
If we take 3960 away from 4720, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

In conclusion, the division gives 27094.83459595 with a balance of 7.6e-07.
