We're dividing 454549 by 2 
We want to divide 454549 by 2.

On to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Step 2:
2 goes into 5 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 4 from 5 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Going ahead to step 3:
14 divided by 2 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 227.0
Subtracting 14 from 14 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Going ahead to step 4:
When dividing 5 by 2, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2272.0
If we subtract 4 from 5, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Let's proceed to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 22727.0
If we subtract 14 from 14, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Moving on to step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 227274.0
Subtracting 8 from 9 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 227274.5
If we take 10 away from 10, 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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 227274.5
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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 227274.5
Subtract 0 from 0 to 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.

After the division, we end up with 227274.5 and a remainder of 0.0.
