We look at the division of 204457 by 25 
We want to figure out the number of times 204457 can be divided by 25.

Advancing to step 1:
2 divided by 25 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 25

Let's proceed to step 2:
25 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 25

On to step 3:
When dividing 204 by 25, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 200 away from 204, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 25

Step 4:
44 divided by 25 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 25 from 44 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 25

Let's proceed to step 5:
The number 25 fits into 195 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 817.0
Deduct 175 from 195 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 25

Going ahead to step 6:
When dividing 207 by 25, we get 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 8178.0
If we take 200 away from 207, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 25 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 8178.2
Subtract 50 from 70 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8178.28
If we subtract 200 from 200, 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.

On to step 9:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8178.28
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.

Moving on to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8178.28
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.

Our division results in 8178.28 with a remaining 0.0.
