We're dividing 620560 by 2 
We want to figure out the number of times 620560 can be divided by 2.

Moving on to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Going ahead to step 2:
2 goes into 2 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Step 3:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 310.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Advancing to step 4:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 3102.0
Subtract 4 from 5 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Step 5:
If we divide 16 by 2, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 31028.0
If we take 16 away from 16, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

On to step 6:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 310280.0
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 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: 310280.0
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.

Advancing to step 8:
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: 310280.0
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.

Our division results in 310280.0 with a remaining 0.0.
