We look at the division of 183944 by 72 
The aim is to understand the frequency of 72 in 183944.

On to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 72

Advancing to step 2:
18 divided by 72 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 72

Let's proceed to step 3:
72 goes into 183 2 times with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 144 from 183 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 72

Moving on to step 4:
72 goes into 399 5 times with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 39 after subtracting 360 from 399.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 72

On to step 5:
When dividing 394 by 72, we get 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 255.0
The remainder is 34 after subtracting 360 from 394.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 72

Moving on to step 6:
If we divide 344 by 72, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 2554.0
The remainder is 56 after subtracting 288 from 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
When dividing 560 by 72, we get 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 2554.7
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
If we divide 560 by 72, we get 7 and a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 2554.77
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 2554.77 with a remaining 0.056.
