We look at the division of 660660 by 75 
We want to figure out the number of times 660660 can be divided by 75.

On to step 1:
75 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 75

Let's proceed to step 2:
66 divided by 75 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 75

Advancing to step 3:
75 goes into 660 8 times with a remainder of 60.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 600 from 660 leaves us with 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 75

Step 4:
75 goes into 606 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 600 from 606 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 75

Going ahead to step 5:
The number 75 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 880.0
Subtract 0 from 66 to get 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 75

On to step 6:
When dividing 660 by 75, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 8808.0
Deduct 600 from 660 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
If we divide 600 by 75, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8808.8
Subtract 600 from 600 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:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8808.8
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.

Let's proceed to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8808.8
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 8808.8 with a remaining 0.0.
