300487 ÷ 25 
We're looking to find how many times 25 goes into 300487.

Moving on to step 1:
3 divided by 25 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 25

On to step 2:
If we divide 30 by 25, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 25 away from 30, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 25

Going ahead to step 3:
When dividing 50 by 25, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 0 after subtracting 50 from 50.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 25

Moving on to step 4:
When dividing 4 by 25, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 25

Let's proceed to step 5:
When dividing 48 by 25, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1201.0
Subtract 25 from 48 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 25

Advancing to step 6:
If we divide 237 by 25, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 12019.0
If we subtract 225 from 237, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
25 goes into 120 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12019.4
The remainder is 20 after subtracting 100 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 12019.48
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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12019.48
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.

On to step 10:
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: 12019.48
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.

Our division results in 12019.48 with a remaining 0.0.
