We divide 323404 by 72
We want to figure out the number of times 323404 can be divided by 72.

Step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 72

Let's proceed to step 2:
If we divide 32 by 72, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 72

Moving on to step 3:
72 can be fit into 323 4 times, resulting in a remainder of 35.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 288 from 323 leaves us with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 72

Moving on to step 4:
When dividing 354 by 72, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 288 from 354 and we're left with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 72

Going ahead to step 5:
The number 72 fits into 660 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 449.0
Subtract 648 from 660 to get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 72

Let's proceed to step 6:
If we divide 124 by 72, we get 1 and a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 4491.0
Subtract 72 from 124 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
The number 72 fits into 520 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 4491.7
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 4491.72
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 72 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 4491.722
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 4491.722 with a remainder of 0.0016.
