443365 divided by 2 
We're looking to find how many times 2 goes into 443365.

Step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

On to step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 4 from 4 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

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
Subtracting 2 from 3 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

On to step 4:
When dividing 13 by 2, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 2216.0
The remainder is 1 after subtracting 12 from 13.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

On to step 5:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 22168.0
Subtracting 16 from 16 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Going ahead to step 6:
5 divided by 2 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 221682.0
Deduct 4 from 5 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.

Let's proceed 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: 221682.5
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 221682.5
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.

Advancing to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 221682.5
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 final outcome is 221682.5, with a leftover of 0.0.
