We look at the division of 487988 by 25 
We want to figure out the number of times 487988 can be divided by 25.

Step 1:
25 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 25

On to step 2:
25 can be fit into 48 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 25 from 48, we get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 25

Going ahead to step 3:
25 can be fit into 237 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 225 away from 237, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 25

On to step 4:
If we divide 129 by 25, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Subtract 125 from 129 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 25

Advancing to step 5:
If we divide 48 by 25, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1951.0
If we take 25 away from 48, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 25

Step 6:
When dividing 238 by 25, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19519.0
Subtracting 225 from 238 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 25 fits into 130 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19519.5
Subtracting 125 from 130 leaves us with 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 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 19519.52
Deduct 50 from 50 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.

Advancing to step 9:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19519.52
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.

Step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19519.52
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.

Our division results in 19519.52 with a remaining 0.0.
