Let's divide 509448 by 25
Our goal is to divide 509448 by 25.

Advancing to step 1:
5 divided by 25 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 25

On to step 2:
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: 2.0
If we take 50 away from 50, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 25

Let's proceed to step 3:
25 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 9, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 25

Let's proceed to step 4:
25 goes into 94 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 203.0
The remainder is 19 after subtracting 75 from 94.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 25

Let's proceed to step 5:
If we divide 194 by 25, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 2037.0
Subtracting 175 from 194 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 25

On to step 6:
198 divided by 25 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 20377.0
Subtracting 175 from 198 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
The number 25 fits into 230 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 20377.9
If we take 225 away from 230, we end up 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.

Advancing to step 8:
25 goes into 50 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 20377.92
The remainder is 0 after subtracting 50 from 50.
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:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20377.92
If we take 0 away from 0, we end up 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:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20377.92
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.

After the division, we end up with 20377.92 and a remainder of 0.0.
