We divide 331591 by 72
We're looking to find how many times 72 goes into 331591.

Moving on to step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 72

Let's proceed to step 2:
The number 72 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 72

Advancing to step 3:
331 divided by 72 is 4 with a remainder of 43.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 288 from 331, we get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 72

Moving on to step 4:
435 divided by 72 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 432 from 435 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 72

Let's proceed to step 5:
If we divide 39 by 72, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 460.0
If we take 0 away from 39, we end up with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 72

On to step 6:
391 divided by 72 is 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 4605.0
The remainder is 31 after subtracting 360 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
72 goes into 310 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 4605.4
If we subtract 288 from 310, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
72 goes into 220 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 4605.43
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 72 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4605.43
Subtracting 0 from 40 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 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4605.4305
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.

Advancing to step 11:
72 goes into 400 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 4605.43055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 4605.43055, with a leftover of 4e-05.
