664648 divided by 8 
We want to figure out the number of times 664648 can be divided by 8.

Moving on to step 1:
8 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 8

On to step 2:
The number 8 fits into 66 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 2 after subtracting 64 from 66.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 8

Step 3:
24 divided by 8 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtract 24 from 24 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 8

Advancing to step 4:
If we divide 6 by 8, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 830.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 8

Let's proceed to step 5:
8 goes into 64 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8308.0
Subtract 64 from 64 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 8

Step 6:
If we divide 8 by 8, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 83081.0
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.

Let's proceed to step 7:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 83081.0
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.

On to step 8:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 83081.0
Deduct 0 from 0 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.

The final result is 83081.0 with a remainder of 0.0.
