We divide 453640 by 25
Our goal is to divide 453640 by 25.

On to step 1:
25 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 25

Moving on to step 2:
The number 25 fits into 45 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 25 from 45 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 25

Step 3:
The number 25 fits into 203 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 3 after subtracting 200 from 203.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 25

On to step 4:
When dividing 36 by 25, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Subtracting 25 from 36 leaves us with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 25

Let's proceed to step 5:
The number 25 fits into 114 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 1814.0
If we subtract 100 from 114, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 25

Let's proceed to step 6:
140 divided by 25 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 18145.0
The remainder is 15 after subtracting 125 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
25 can be fit into 150 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 18145.6
Deduct 150 from 150 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 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18145.6
If we subtract 0 from 0, 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.

Going ahead to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18145.6
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.

In conclusion, the division gives 18145.6 with a balance of 0.0.
