We look at the division of 30915 by 72 
Let's see how many times 72 fits into 30915.

Let's proceed 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.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 72

Moving on to step 2:
If we divide 30 by 72, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 72

Let's proceed to step 3:
If we divide 309 by 72, we get 4 and a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 288 from 309 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 72

Advancing to step 4:
211 divided by 72 is 2 with a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 144 from 211 to get 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 72

Let's proceed to step 5:
When dividing 675 by 72, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 429.0
If we subtract 648 from 675, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 6:
72 goes into 270 3 times with a remainder of 54.
The next digit of our result is 3. 
Result so far: 429.3
Subtracting 216 from 270 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
72 can be fit into 540 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 429.37
If we subtract 504 from 540, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 72, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 429.375
Deduct 360 from 360 and we're left 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.

Let's proceed to step 9:
72 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 429.375
Deduct 0 from 0 and we're left 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:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 429.375
Subtracting 0 from 0 leaves us 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.

The final result is 429.375 with a remainder of 0.0.
