We're dividing 723609 by 75 
We want to divide 723609 by 75.

Advancing to step 1:
7 divided by 75 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 75

Step 2:
The number 75 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 75

Going ahead to step 3:
If we divide 723 by 75, we get 9 and a remainder of 48.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 675 from 723 leaves us with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 75

On to step 4:
75 goes into 486 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtracting 450 from 486 leaves us with 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 75

Moving on to step 5:
If we divide 360 by 75, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 964.0
If we subtract 300 from 360, we get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 75

Step 6:
609 divided by 75 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 9648.0
If we take 600 away from 609, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 75 fits into 90 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 9648.1
Deduct 75 from 90 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 9648.12
If we take 150 away from 150, 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.

Going ahead to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9648.12
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.

Going ahead to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9648.12
Subtract 0 from 0 to 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.

Our division results in 9648.12 with a remaining 0.0.
