We look at the division of 664507 by 25 
Let's see how many times 25 fits into 664507.

Going ahead to step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 25

Advancing to step 2:
66 divided by 25 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 50 from 66, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 25

Going ahead to step 3:
164 divided by 25 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 150 from 164 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 25

Advancing to step 4:
145 divided by 25 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Deduct 125 from 145 and we're left with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 25

Going ahead to step 5:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2658.0
The remainder is 0 after subtracting 200 from 200.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 25

Advancing to step 6:
When dividing 7 by 25, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 26580.0
Subtracting 0 from 7 leaves us 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.

Going ahead to step 7:
25 goes into 70 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 26580.2
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.

Step 8:
200 divided by 25 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 26580.28
Subtract 200 from 200 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.

Advancing to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26580.28
The remainder is 0 after subtracting 0 from 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:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26580.28
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.

After the division, we end up with 26580.28 and a remainder of 0.0.
