Let's divide 644026 by 2
We want to figure out the number of times 644026 can be divided by 2.

Going ahead to step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 4 from 4 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Moving on to step 3:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 322.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Going ahead to step 4:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3220.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Let's proceed to step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 32201.0
If we take 2 away from 2, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Moving on to step 6:
If we divide 6 by 2, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 322013.0
If we take 6 away from 6, 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.

Moving on to step 7:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 322013.0
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.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 322013.0
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.

The final result is 322013.0 with a remainder of 0.0.
