Let's divide 436408 by 2
We want to figure out the number of times 436408 can be divided by 2.

Step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

On to step 2:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 2 away from 3, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Advancing to step 3:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Subtract 16 from 16 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Let's proceed to step 4:
4 divided by 2 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2182.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Let's proceed to step 5:
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: 21820.0
If we take 0 away from 0, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Advancing to step 6:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 218204.0
Subtract 8 from 8 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.

On to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 218204.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 218204.0
Deduct 0 from 0 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.

After the division, we end up with 218204.0 and a remainder of 0.0.
