Let's divide 397080 by 25
We're looking to find how many times 25 goes into 397080.

Going ahead to step 1:
The number 25 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 25

Step 2:
39 divided by 25 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 25 from 39 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 25

Advancing to step 3:
147 divided by 25 is 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 125 from 147 and we're left with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 25

Step 4:
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: 158.0
The remainder is 20 after subtracting 200 from 220.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 25

On to step 5:
208 divided by 25 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 1588.0
If we take 200 away from 208, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 25

Moving on to step 6:
The number 25 fits into 80 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 15883.0
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 25, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 15883.2
If we subtract 50 from 50, 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.

Step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15883.2
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.

Step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15883.2
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.

The final result is 15883.2 with a remainder of 0.0.
