We're dividing 20922980 by 813 
Let's see how many times 813 fits into 20922980.

Advancing to step 1:
813 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.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 813

Let's proceed to step 2:
When dividing 20 by 813, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 813

Going ahead to step 3:
If we divide 209 by 813, we get 0 and a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Grab the next digit (2) from the dividend, add it to 209, then carry on: 2092 / 813

Going ahead to step 4:
2092 divided by 813 is 2 with a remainder of 466.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1626 from 2092 and we're left with 466.
Append the next digit (2) from the dividend to 466 and continue with: 4662 / 813

Let's proceed to step 5:
4662 divided by 813 is 5 with a remainder of 597.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 4065 from 4662 and we're left with 597.
Include the next digit (9) from the dividend after 597, then repeat: 5979 / 813

Advancing to step 6:
The number 813 fits into 5979 7 times, leaving a remainder of 288.
Put 7 as the next digit of the answer. 
Result so far: 257.0
Deduct 5691 from 5979 and we're left with 288.
Append the next digit (8) from the dividend to 288 and continue with: 2888 / 813

Step 7:
If we divide 2888 by 813, we get 3 and a remainder of 449.
Put 3 as the next digit of the answer. 
Result so far: 2573.0
If we take 2439 away from 2888, we end up with 449.
Take the next digit (0) from the dividend and append it to 449, then repeat: 4490 / 813

Moving on to step 8:
The number 813 fits into 4490 5 times, leaving a remainder of 425.
The next digit of our result is 5. 
Result so far: 25735.0
The remainder is 425 after subtracting 4065 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 9:
813 can be fit into 4250 5 times, resulting in a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 25735.5
Subtracting 4065 from 4250 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
813 can be fit into 1850 2 times, resulting in a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 25735.52
Subtract 1626 from 1850 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 11:
813 can be fit into 2240 2 times, resulting in a remainder of 614.
Write down 2 as next digit of the result. 
Result so far: 25735.522
Subtract 1626 from 2240 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The final result is 25735.522 with a remainder of 0.0614.
