We look at the division of 447403 by 2 
We want to figure out the number of times 447403 can be divided by 2.

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
Subtract 4 from 4 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Going ahead to step 2:
4 divided by 2 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 2

On to step 3:
2 goes into 7 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 223.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Step 4:
14 divided by 2 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 2237.0
Deduct 14 from 14 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Let's proceed to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22370.0
If we subtract 0 from 0, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Moving on to step 6:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 223701.0
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.

Going ahead to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 223701.5
Deduct 10 from 10 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.

On to step 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 223701.5
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.

Moving on to step 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 223701.5
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.

The final result is 223701.5 with a remainder of 0.0.
