We look at the division of 488570 by 25 
We're looking to find how many times 25 goes into 488570.

On to step 1:
The number 25 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 25

Going ahead to step 2:
The number 25 fits into 48 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
If we take 25 away from 48, we end up with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 25

Going ahead to step 3:
The number 25 fits into 238 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 225 away from 238, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 25

On to step 4:
The number 25 fits into 135 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtract 125 from 135 to get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 25

Advancing to step 5:
25 can be fit into 107 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1954.0
The remainder is 7 after subtracting 100 from 107.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 25

Advancing to step 6:
If we divide 70 by 25, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 19542.0
Subtracting 50 from 70 leaves us 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.

Step 7:
200 divided by 25 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 19542.8
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.

Moving on to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19542.8
Deduct 0 from 0 and we're left 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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19542.8
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 19542.8 and a remainder of 0.0.
