Let's divide 331228 by 72
We want to divide 331228 by 72.

Advancing to step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 72

Moving on to step 2:
If we divide 33 by 72, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 72

Let's proceed to step 3:
If we divide 331 by 72, we get 4 and a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 288 from 331 to get 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 72

Step 4:
72 goes into 432 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 432 from 432, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 72

Advancing to step 5:
When dividing 2 by 72, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 460.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 72

Moving on to step 6:
72 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 4600.0
If we subtract 0 from 28, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
If we divide 280 by 72, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 4600.3
If we take 216 away from 280, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
When dividing 640 by 72, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 4600.38
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
640 divided by 72 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 4600.388
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 4600.388, with a leftover of 0.0064.
