We divide 742636 by 2
We want to figure out the number of times 742636 can be divided by 2.

Let's proceed to step 1:
When dividing 7 by 2, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 6 from 7 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Moving on to step 2:
If we divide 14 by 2, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 0 after subtracting 14 from 14.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

On to step 3:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 371.0
Subtract 2 from 2 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Moving on to step 4:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3713.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Let's proceed to step 5:
3 divided by 2 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 37131.0
If we take 2 away from 3, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

On to step 6:
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: 371318.0
If we subtract 16 from 16, 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.

Let's proceed to step 7:
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: 371318.0
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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 371318.0
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.

After the division, we end up with 371318.0 and a remainder of 0.0.
