We look at the division of 664569 by 75 
We're looking to find how many times 75 goes into 664569.

Moving on to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
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:
75 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 75

Let's proceed to step 3:
75 can be fit into 664 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 600 from 664, we get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 75

Advancing to step 4:
645 divided by 75 is 8 with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtract 600 from 645 to get 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 75

On to step 5:
The number 75 fits into 456 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 886.0
If we take 450 away from 456, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 75

Let's proceed to step 6:
The number 75 fits into 69 0 times, leaving a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 8860.0
If we subtract 0 from 69, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
75 goes into 690 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 8860.9
If we take 675 away from 690, we end up with 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:
When dividing 150 by 75, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 8860.92
Subtracting 150 from 150 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.

Advancing to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8860.92
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.

Going ahead to step 10:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8860.92
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.

The final outcome is 8860.92, with a leftover of 0.0.
