668289 ÷ 75 
We want to figure out the number of times 668289 can be divided by 75.

On to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 75

Step 2:
The number 75 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 75

Moving on to step 3:
When dividing 668 by 75, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 600 from 668, we get 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 75

On to step 4:
682 divided by 75 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 89.0
The remainder is 7 after subtracting 675 from 682.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 75

Advancing to step 5:
75 goes into 78 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 891.0
The remainder is 3 after subtracting 75 from 78.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 75

Advancing to step 6:
75 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 8910.0
Subtracting 0 from 39 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
75 goes into 390 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8910.5
Subtract 375 from 390 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 75 fits into 150 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 8910.52
If we subtract 150 from 150, 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.

Going ahead to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8910.52
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.

Going ahead to step 10:
75 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8910.52
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.

Our division results in 8910.52 with a remaining 0.0.
