We're dividing 575515 by 75 
We want to figure out the number of times 575515 can be divided by 75.

Going ahead to step 1:
The number 75 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 75

Advancing to step 2:
75 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 75

Moving on to step 3:
When dividing 575 by 75, we get 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 7.0
If we take 525 away from 575, we end up with 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 75

On to step 4:
75 can be fit into 505 6 times, resulting in a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 450 from 505 to get 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 75

Moving on to step 5:
When dividing 551 by 75, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 767.0
If we subtract 525 from 551, we get 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 75

Moving on to step 6:
If we divide 265 by 75, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 7673.0
If we subtract 225 from 265, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
If we divide 400 by 75, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 7673.5
If we subtract 375 from 400, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
250 divided by 75 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 7673.53
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 7673.533
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 7673.533 and a remainder of 0.0025.
