We look at the division of 443070 by 2 
Let's see how many times 2 fits into 443070.

Let's proceed to step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Moving on to step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 4 from 4 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Moving on to step 3:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
Deduct 2 from 3 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Going ahead to step 4:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2215.0
If we subtract 10 from 10, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

On to step 5:
When dividing 7 by 2, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 22153.0
Deduct 6 from 7 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Advancing to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 221535.0
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.

Step 7:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 221535.0
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 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 221535.0
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 final result is 221535.0 with a remainder of 0.0.
