We're dividing 199559 by 25 
We want to figure out the number of times 199559 can be divided by 25.

Let's proceed to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 25

On to step 2:
When dividing 19 by 25, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 25

Advancing to step 3:
When dividing 199 by 25, we get 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 24 after subtracting 175 from 199.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 25

Going ahead to step 4:
25 can be fit into 245 9 times, resulting in a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 79.0
Deduct 225 from 245 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 25

Let's proceed to step 5:
205 divided by 25 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 798.0
The remainder is 5 after subtracting 200 from 205.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 25

Advancing to step 6:
25 goes into 59 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 7982.0
Subtracting 50 from 59 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 25, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 7982.3
Subtracting 75 from 90 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:
25 goes into 150 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 7982.36
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.

Let's proceed 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: 7982.36
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.

On to step 10:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7982.36
If we subtract 0 from 0, 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.

After the division, we end up with 7982.36 and a remainder of 0.0.
