We're dividing 387 by 72 
The aim is to understand the frequency of 72 in 387.

Step 1:
3 divided by 72 is 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.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 72

Advancing to step 2:
72 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 72

Going ahead to step 3:
If we divide 387 by 72, we get 5 and a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 27 after subtracting 360 from 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 4:
270 divided by 72 is 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 5.3
The remainder is 54 after subtracting 216 from 270.
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 5:
72 goes into 540 7 times with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 5.37
Subtracting 504 from 540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 6:
360 divided by 72 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.375
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 72 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5.375
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.

On to step 8:
The number 72 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5.375 with a remaining 0.0.
