640335 divided by 75 
Our goal is to divide 640335 by 75.

Advancing to step 1:
6 divided by 75 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 75

Going ahead to step 2:
75 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 75

Moving on to step 3:
75 can be fit into 640 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 40 after subtracting 600 from 640.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 75

Going ahead to step 4:
403 divided by 75 is 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 375 away from 403, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 75

Let's proceed to step 5:
The number 75 fits into 283 3 times, leaving a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 853.0
Subtract 225 from 283 to get 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 75

Step 6:
75 can be fit into 585 7 times, resulting in a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 8537.0
If we subtract 525 from 585, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
The number 75 fits into 600 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 8537.8
Deduct 600 from 600 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 8:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8537.8
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:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8537.8
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 quotient of the division is 8537.8, and the remainder is 0.0.
