We look at the division of 71876 by 72 
The aim is to understand the frequency of 72 in 71876.

Advancing to step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 72

Step 2:
The number 72 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 72

Advancing to step 3:
72 can be fit into 718 9 times, resulting in a remainder of 70.
The next digit of our result is 9. 
Result so far: 9.0
If we take 648 away from 718, we end up with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 72

Advancing to step 4:
The number 72 fits into 707 9 times, leaving a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 648 from 707 to get 59.
Grab the next digit (6) from the dividend, add it to 59, then carry on: 596 / 72

Let's proceed to step 5:
If we divide 596 by 72, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
Subtract 576 from 596 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 6:
72 goes into 200 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 998.2
The remainder is 56 after subtracting 144 from 200.
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 7:
560 divided by 72 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 998.27
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:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 998.277
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.

Our division results in 998.277 with a remaining 0.0056.
