We look at the division of 531702 by 72 
The aim is to understand the frequency of 72 in 531702.

Moving on to step 1:
5 divided by 72 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 72

Advancing to step 2:
72 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 72

On to step 3:
If we divide 531 by 72, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 504 from 531 leaves us with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 72

Let's proceed to step 4:
72 goes into 277 3 times with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 216 from 277 leaves us with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 72

Going ahead to step 5:
If we divide 610 by 72, we get 8 and a remainder of 34.
The next digit of our result is 8. 
Result so far: 738.0
Subtract 576 from 610 to get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 72

Let's proceed to step 6:
72 can be fit into 342 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 7384.0
If we subtract 288 from 342, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
When dividing 540 by 72, we get 7 with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7384.7
Subtract 504 from 540 to 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.

Step 8:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7384.75
Subtracting 360 from 360 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.

Going ahead to step 9:
0 divided by 72 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7384.75
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.

Moving on to step 10:
0 divided by 72 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7384.75
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 7384.75 with a remainder of 0.0.
