We look at the division of 311584 by 72 
We're looking to find how many times 72 goes into 311584.

Advancing to step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 72

Advancing to step 2:
72 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 72

Advancing to step 3:
72 goes into 311 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 288 from 311 leaves us with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 72

Let's proceed to step 4:
The number 72 fits into 235 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 216 from 235 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 72

Going ahead to step 5:
If we divide 198 by 72, we get 2 and a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 432.0
If we subtract 144 from 198, we get 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 72

Moving on to step 6:
72 goes into 544 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 4327.0
Subtracting 504 from 544 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
72 goes into 400 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4327.5
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 4327.55
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 4327.55 with a remaining 0.04.
