Let's divide 640228 by 2
We want to figure out the number of times 640228 can be divided by 2.

Let's proceed to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Advancing to step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Going ahead to step 3:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 320.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Moving on to step 4:
2 divided by 2 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 3201.0
If we subtract 2 from 2, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Advancing to step 5:
When dividing 2 by 2, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 32011.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Let's proceed to step 6:
2 can be fit into 8 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 320114.0
Deduct 8 from 8 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.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 320114.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 320114.0
If we subtract 0 from 0, 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.

After the division, we end up with 320114.0 and a remainder of 0.0.
