We divide 385120 by 72
The aim is to understand the frequency of 72 in 385120.

Going ahead to step 1:
If we divide 3 by 72, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 72

On to step 2:
72 goes into 38 0 times with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 72

On to step 3:
385 divided by 72 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 360 away from 385, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 72

Let's proceed to step 4:
72 can be fit into 251 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 216 from 251 leaves us with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 72

Moving on to step 5:
352 divided by 72 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 534.0
Deduct 288 from 352 and we're left with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 72

Moving on to step 6:
When dividing 640 by 72, we get 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 5348.0
If we take 576 away from 640, 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.

Going ahead to step 7:
72 goes into 640 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 5348.8
If we subtract 576 from 640, we 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.

Advancing to step 8:
If we divide 640 by 72, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 5348.88
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 result is 5348.88 with a remainder of 0.064.
