We're dividing 656391 by 2 
We want to figure out the number of times 656391 can be divided by 2.

Moving on to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Step 2:
2 goes into 5 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 4 from 5 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Advancing to step 3:
16 divided by 2 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 328.0
If we subtract 16 from 16, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Let's proceed to step 4:
If we divide 3 by 2, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3281.0
Subtract 2 from 3 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Let's proceed to step 5:
19 divided by 2 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 32819.0
Deduct 18 from 19 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

On to step 6:
2 goes into 11 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 328195.0
Subtracting 10 from 11 leaves us 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.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 328195.5
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.

Step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 328195.5
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.

On to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 328195.5
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.

After the division, we end up with 328195.5 and a remainder of 0.0.
