We're dividing 454850 by 25 
We're looking to find how many times 25 goes into 454850.

Let's proceed to step 1:
When dividing 4 by 25, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 25

Going ahead to step 2:
25 can be fit into 45 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 25 from 45 and we're left with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 25

Moving on to step 3:
204 divided by 25 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 4 after subtracting 200 from 204.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 25

Step 4:
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: 181.0
Subtracting 25 from 48 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 25

Step 5:
When dividing 235 by 25, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 1819.0
If we take 225 away from 235, we end up with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 25

Moving on to step 6:
If we divide 100 by 25, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 18194.0
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18194.0
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.

Advancing to step 8:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18194.0
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.

The quotient of the division is 18194.0, and the remainder is 0.0.
