303088 ÷ 25 
We want to figure out the number of times 303088 can be divided by 25.

Going ahead to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 25

Going ahead to step 2:
30 divided by 25 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 25 from 30.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 25

On to step 3:
25 goes into 53 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 50 from 53, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 25

Step 4:
When dividing 30 by 25, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtract 25 from 30 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 25

Step 5:
25 goes into 58 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1212.0
If we subtract 50 from 58, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 25

Going ahead to step 6:
If we divide 88 by 25, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 12123.0
If we subtract 75 from 88, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
25 goes into 130 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12123.5
Subtract 125 from 130 to 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.

On to step 8:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12123.52
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.

Let's proceed to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12123.52
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.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12123.52
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.

After the division, we end up with 12123.52 and a remainder of 0.0.
