Let's divide 455863 by 2
Let's see how many times 2 fits into 455863.

Moving on to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Moving on to step 2:
5 divided by 2 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 4 from 5 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Going ahead to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
If we take 14 away from 15, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Moving on to step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2279.0
Subtract 18 from 18 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Step 5:
6 divided by 2 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 22793.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Going ahead to step 6:
When dividing 3 by 2, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 227931.0
If we subtract 2 from 3, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 2 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 227931.5
Subtracting 10 from 10 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.

On to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 227931.5
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.

Step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 227931.5
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.

The quotient of the division is 227931.5, and the remainder is 0.0.
