We're dividing 725440 by 75 
Our goal is to divide 725440 by 75.

On to step 1:
75 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 75

On to step 2:
75 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 75

Going ahead to step 3:
75 can be fit into 725 9 times, resulting in a remainder of 50.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 675 from 725, we get 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 75

On to step 4:
When dividing 504 by 75, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtract 450 from 504 to get 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 75

On to step 5:
544 divided by 75 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 967.0
If we take 525 away from 544, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 75

On to step 6:
The number 75 fits into 190 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 9672.0
The remainder is 40 after subtracting 150 from 190.
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.
The number 5 becomes the next digit in our result. 
Result so far: 9672.5
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.

Advancing to step 8:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 9672.53
Deduct 225 from 250 and we're left 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.

Advancing to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9672.533
If we take 225 away from 250, we end up 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.

After the division, we end up with 9672.533 and a remainder of 0.0025.
