We divide 457303 by 2
We want to figure out the number of times 457303 can be divided by 2.

Advancing to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Going ahead to step 2:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 1 after subtracting 4 from 5.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

On to step 3:
If we divide 17 by 2, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 228.0
Deduct 16 from 17 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Going ahead to step 4:
If we divide 13 by 2, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 2286.0
If we subtract 12 from 13, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

On to step 5:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 22865.0
Subtract 10 from 10 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

On to step 6:
3 divided by 2 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 228651.0
Deduct 2 from 3 and we're left 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.

Moving on to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 228651.5
Subtract 10 from 10 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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 228651.5
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.

Let's proceed to step 9:
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: 228651.5
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.

The quotient of the division is 228651.5, and the remainder is 0.0.
