We look at the division of 209974 by 25 
We're looking to find how many times 25 goes into 209974.

Moving on to step 1:
2 divided by 25 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 25

Going ahead to step 2:
The number 25 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 25

Step 3:
If we divide 209 by 25, we get 8 and a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 9 after subtracting 200 from 209.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 25

Let's proceed to step 4:
The number 25 fits into 99 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtracting 75 from 99 leaves us with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 25

Going ahead to step 5:
25 goes into 247 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 839.0
Subtracting 225 from 247 leaves us with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 25

Moving on to step 6:
224 divided by 25 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 8398.0
Subtract 200 from 224 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
25 can be fit into 240 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 8398.9
Subtracting 225 from 240 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
If we divide 150 by 25, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 8398.96
If we subtract 150 from 150, we 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.

Advancing to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8398.96
Subtracting 0 from 0 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 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8398.96
If we take 0 away from 0, we end up 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 outcome is 8398.96, with a leftover of 0.0.
