We look at the division of 195922 by 72 
The aim is to understand the frequency of 72 in 195922.

On to step 1:
72 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 72

Moving on to step 2:
When dividing 19 by 72, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 72

Advancing to step 3:
The number 72 fits into 195 2 times, leaving a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 144 from 195 to get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 72

Let's proceed to step 4:
519 divided by 72 is 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 504 from 519 leaves us with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 72

Let's proceed to step 5:
If we divide 152 by 72, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Subtract 144 from 152 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 72

Moving on to step 6:
82 divided by 72 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2721.0
The remainder is 10 after subtracting 72 from 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
When dividing 100 by 72, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 2721.1
Subtracting 72 from 100 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 72, we get 3 and a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 2721.13
If we subtract 216 from 280, 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.

Step 9:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 2721.138
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
72 goes into 640 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 2721.1388
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.

Our division results in 2721.1388 with a remaining 0.00064.
