We divide 20644 by 99
We're looking to find how many times 99 goes into 20644.

Going ahead to step 1:
99 can be fit into 2 0 times, resulting in 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.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 99

Let's proceed to step 2:
When dividing 20 by 99, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 99

Going ahead to step 3:
99 can be fit into 206 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 198 from 206, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 99

Step 4:
The number 99 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 99

On to step 5:
When dividing 844 by 99, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 208.0
If we subtract 792 from 844, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 6:
The number 99 fits into 520 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 208.5
Subtract 495 from 520 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 99, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 208.52
If we subtract 198 from 250, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
The number 99 fits into 520 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 208.525
If we subtract 495 from 520, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
If we divide 250 by 99, we get 2 and a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 208.5252
Subtract 198 from 250 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
99 goes into 520 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 208.52525
Deduct 495 from 520 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
250 divided by 99 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 208.525252
Subtract 198 from 250 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
When dividing 520 by 99, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 208.5252525
The remainder is 25 after subtracting 495 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
250 divided by 99 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 208.52525252
If we subtract 198 from 250, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 208.52525252 with a remaining 5.2e-08.
