We look at the division of 664542 by 75 
We're looking to find how many times 75 goes into 664542.

Let's proceed to step 1:
75 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 75

Let's proceed to step 2:
The number 75 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 75

Moving on to step 3:
The number 75 fits into 664 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 64 after subtracting 600 from 664.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 75

Going ahead to step 4:
645 divided by 75 is 8 with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 45 after subtracting 600 from 645.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 75

Let's proceed to step 5:
When dividing 454 by 75, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 886.0
Deduct 450 from 454 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 75

Advancing to step 6:
42 divided by 75 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 8860.0
The remainder is 42 after subtracting 0 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
420 divided by 75 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 8860.5
Subtract 375 from 420 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
The number 75 fits into 450 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 8860.56
If we subtract 450 from 450, 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.

Step 9:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8860.56
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.

Advancing to step 10:
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: 8860.56
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.

After the division, we end up with 8860.56 and a remainder of 0.0.
