We're dividing 209900 by 80 
We're looking to find how many times 80 goes into 209900.

Let's proceed to step 1:
80 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 80

Advancing to step 2:
The number 80 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 80

On to step 3:
When dividing 209 by 80, we get 2 with a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 160 from 209 leaves us with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 80

Step 4:
80 goes into 499 6 times with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 19 after subtracting 480 from 499.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 80

On to step 5:
If we divide 190 by 80, we get 2 and a remainder of 30.
The next digit of our result is 2. 
Result so far: 262.0
Subtract 160 from 190 to get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 80

Let's proceed to step 6:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 2623.0
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 2623.7
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2623.75
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2623.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2623.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2623.75 with a remainder of 0.0.
