We're dividing 21553287 by 797 
Our goal is to divide 21553287 by 797.

Advancing to step 1:
When dividing 2 by 797, we get 0 with 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 797

On to step 2:
797 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
If we take 0 away from 21, we end up with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 797

Moving on to step 3:
The number 797 fits into 215 0 times, leaving a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Take the next digit (5) from the dividend and append it to 215, then repeat: 2155 / 797

Going ahead to step 4:
If we divide 2155 by 797, we get 2 and a remainder of 561.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1594 from 2155 and we're left with 561.
Append the next digit (3) from the dividend to 561 and continue with: 5613 / 797

On to step 5:
If we divide 5613 by 797, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 5579 from 5613 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 797

Let's proceed to step 6:
797 goes into 342 0 times with a remainder of 342.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we take 0 away from 342, we end up with 342.
Fetch the next digit (8) from the dividend, attach it to 342 and continue: 3428 / 797

Going ahead to step 7:
If we divide 3428 by 797, we get 4 and a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 2704.0
If we subtract 3188 from 3428, we get 240.
Bring next digit (7) of the dividend behind the 240 and repeat the process: 2407 / 797

Advancing to step 8:
797 can be fit into 2407 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 27043.0
Deduct 2391 from 2407 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
If we divide 160 by 797, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 27043.0
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
The number 797 fits into 1600 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 27043.02
If we take 1594 away from 1600, 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.

Moving on to step 11:
When dividing 60 by 797, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 27043.02
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.

Step 12:
If we divide 600 by 797, we get 0 and a remainder of 600.
The next digit of our result is 0. 
Result so far: 27043.02
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 27043.02 with a remainder of 0.006.
