We're dividing 40843681 by 2 
We want to figure out the number of times 40843681 can be divided by 2.

Advancing to step 1:
4 divided by 2 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Going ahead to step 2:
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: 20.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Step 3:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 204.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Going ahead to step 4:
If we divide 4 by 2, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2042.0
If we take 4 away from 4, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Step 5:
If we divide 3 by 2, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 20421.0
If we subtract 2 from 3, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

On to step 6:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 204218.0
Subtracting 16 from 16 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Going ahead to step 7:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2042184.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Going ahead to step 8:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 20421840.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 20421840.5
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.

Advancing to step 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20421840.5
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.

Moving on to step 11:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 20421840.5
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.

After the division, we end up with 20421840.5 and a remainder of 0.0.
