640028 divided by 8 
Let's see how many times 8 fits into 640028.

Let's proceed to step 1:
6 divided by 8 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 8

Let's proceed to step 2:
64 divided by 8 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 64 away from 64, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 8

Step 3:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we subtract 0 from 0, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 8

Step 4:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 800.0
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 / 8

Going ahead to step 5:
2 divided by 8 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 8000.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 8

Moving on to step 6:
The number 8 fits into 28 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 80003.0
If we subtract 24 from 28, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 80003.5
The remainder is 0 after subtracting 40 from 40.
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 8:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80003.5
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.

On to step 9:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80003.5
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.

In conclusion, the division gives 80003.5 with a balance of 0.0.
