We're dividing 20890099 by 797 
Let's see how many times 797 fits into 20890099.

On to step 1:
If we divide 2 by 797, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 797

On to step 2:
When dividing 20 by 797, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 797

On to step 3:
797 goes into 208 0 times with a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 208, we end up with 208.
Fetch the next digit (9) from the dividend, attach it to 208 and continue: 2089 / 797

Going ahead to step 4:
2089 divided by 797 is 2 with a remainder of 495.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1594 from 2089, we get 495.
Bring next digit (0) of the dividend behind the 495 and repeat the process: 4950 / 797

Advancing to step 5:
797 can be fit into 4950 6 times, resulting in a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 4782 away from 4950, we end up with 168.
Fetch the next digit (0) from the dividend, attach it to 168 and continue: 1680 / 797

On to step 6:
797 can be fit into 1680 2 times, resulting in a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
Subtract 1594 from 1680 to get 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 797

Moving on to step 7:
When dividing 869 by 797, we get 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 2621.0
Subtracting 797 from 869 leaves us with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 797

Going ahead to step 8:
797 goes into 729 0 times with a remainder of 729.
The number 0 becomes the next digit in our result. 
Result so far: 26210.0
If we subtract 0 from 729, we get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Moving on to step 9:
The number 797 fits into 7290 9 times, leaving a remainder of 117.
Put 9 as the next digit of the answer. 
Result so far: 26210.9
If we subtract 7173 from 7290, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 10:
If we divide 1170 by 797, we get 1 and a remainder of 373.
The number 1 becomes the next digit in our result. 
Result so far: 26210.91
Deduct 797 from 1170 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 11:
797 can be fit into 3730 4 times, resulting in a remainder of 542.
Write down 4 as next digit of the result. 
Result so far: 26210.914
Subtracting 3188 from 3730 leaves us with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 12:
When dividing 5420 by 797, we get 6 with a remainder of 638.
Write down 6 as next digit of the result. 
Result so far: 26210.9146
If we take 4782 away from 5420, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 13:
6380 divided by 797 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 26210.91468
If we take 6376 away from 6380, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
797 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 26210.91468
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
400 divided by 797 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 26210.91468
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 26210.91468 with a remainder of 4e-06.
