We're dividing 663797 by 25 
Let's see how many times 25 fits into 663797.

Advancing to step 1:
If we divide 6 by 25, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 25

Step 2:
The number 25 fits into 66 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 50 away from 66, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 25

Step 3:
25 goes into 163 6 times with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 150 from 163 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 25

On to step 4:
137 divided by 25 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 265.0
Subtract 125 from 137 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 25

Moving on to step 5:
25 goes into 129 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 2655.0
If we subtract 125 from 129, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 25

Step 6:
47 divided by 25 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 26551.0
Deduct 25 from 47 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 25, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 26551.8
Deduct 200 from 220 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 26551.88
The remainder is 0 after subtracting 200 from 200.
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 26551.88 and a remainder of 0.0.
