We divide 21809138 by 791
We want to divide 21809138 by 791.

Advancing to step 1:
The number 791 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 791

Moving on to step 2:
21 divided by 791 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 791

Advancing to step 3:
When dividing 218 by 791, we get 0 with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Append the next digit (0) from the dividend to 218 and continue with: 2180 / 791

Moving on to step 4:
791 goes into 2180 2 times with a remainder of 598.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1582 away from 2180, we end up with 598.
Bring next digit (9) of the dividend behind the 598 and repeat the process: 5989 / 791

Let's proceed to step 5:
5989 divided by 791 is 7 with a remainder of 452.
The next digit of our result is 7. 
Result so far: 27.0
If we take 5537 away from 5989, we end up with 452.
Fetch the next digit (1) from the dividend, attach it to 452 and continue: 4521 / 791

Going ahead to step 6:
791 can be fit into 4521 5 times, resulting in a remainder of 566.
The number 5 becomes the next digit in our result. 
Result so far: 275.0
Subtract 3955 from 4521 to get 566.
Grab the next digit (3) from the dividend, add it to 566, then carry on: 5663 / 791

Going ahead to step 7:
791 can be fit into 5663 7 times, resulting in a remainder of 126.
Record the quotient 7 as the next digit in the result. 
Result so far: 2757.0
Deduct 5537 from 5663 and we're left with 126.
Include the next digit (8) from the dividend after 126, then repeat: 1268 / 791

Going ahead to step 8:
791 can be fit into 1268 1 times, resulting in a remainder of 477.
The number 1 becomes the next digit in our result. 
Result so far: 27571.0
If we take 791 away from 1268, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 9:
4770 divided by 791 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 27571.6
Subtracting 4746 from 4770 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 791, we get 0 and a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 27571.6
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
When dividing 2400 by 791, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 27571.603
Deduct 2373 from 2400 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
If we divide 270 by 791, we get 0 and a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 27571.603
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
When dividing 2700 by 791, we get 3 with a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 27571.60303
Deduct 2373 from 2700 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 14:
The number 791 fits into 3270 4 times, leaving a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 27571.603034
Subtract 3164 from 3270 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 15:
The number 791 fits into 1060 1 times, leaving a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 27571.6030341
The remainder is 269 after subtracting 791 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 16:
791 goes into 2690 3 times with a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 27571.60303413
Deduct 2373 from 2690 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Our division results in 27571.60303413 with a remaining 3.17e-07.
