We divide 443588 by 2
We want to figure out the number of times 443588 can be divided by 2.

Step 1:
4 divided by 2 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

On to step 2:
4 divided by 2 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Advancing to step 3:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 221.0
If we take 2 away from 3, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Let's proceed to step 4:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 2217.0
If we take 14 away from 15, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Let's proceed to step 5:
18 divided by 2 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 22179.0
Deduct 18 from 18 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Moving on to step 6:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 221794.0
If we subtract 8 from 8, 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.

Moving on to step 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 221794.0
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 8:
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: 221794.0
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 221794.0 and a remainder of 0.0.
