Let's divide 618597 by 25
We're looking to find how many times 25 goes into 618597.

Going ahead to step 1:
25 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 25

On to step 2:
25 goes into 61 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 50 from 61, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 25

Going ahead to step 3:
118 divided by 25 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 18 after subtracting 100 from 118.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 25

Step 4:
If we divide 185 by 25, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 247.0
Subtracting 175 from 185 leaves us with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 25

Advancing to step 5:
If we divide 109 by 25, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 2474.0
Subtracting 100 from 109 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 25

Advancing to step 6:
25 can be fit into 97 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 24743.0
Deduct 75 from 97 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.

Going ahead to step 7:
25 can be fit into 220 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 24743.8
Subtract 200 from 220 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.

Going ahead to step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 24743.88
Subtracting 200 from 200 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.

The final result is 24743.88 with a remainder of 0.0.
