We're dividing 717880 by 75 
We want to figure out the number of times 717880 can be divided by 75.

Step 1:
75 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 75

Advancing to step 2:
75 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 75

Moving on to step 3:
75 goes into 717 9 times with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 675 away from 717, we end up with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 75

Moving on to step 4:
75 goes into 428 5 times with a remainder of 53.
The next digit of our result is 5. 
Result so far: 95.0
Subtract 375 from 428 to get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 75

Moving on to step 5:
75 goes into 538 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 957.0
Deduct 525 from 538 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 75

Step 6:
75 goes into 130 1 times with a remainder of 55.
The next digit of our result is 1. 
Result so far: 9571.0
Subtract 75 from 130 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
75 can be fit into 550 7 times, resulting in a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 9571.7
Subtract 525 from 550 to 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 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9571.73
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.
Use 3 as the next digit of our solution. 
Result so far: 9571.733
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 9571.733 with a remainder of 0.0025.
