Let's divide 13723271 by 72
The aim is to understand the frequency of 72 in 13723271.

Step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 72

Moving on to step 2:
72 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 72

Let's proceed to step 3:
72 can be fit into 137 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 137, we get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 72

Moving on to step 4:
The number 72 fits into 652 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 648 from 652 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 72

Advancing to step 5:
The number 72 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we subtract 0 from 43, we get 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 72

Going ahead to step 6:
If we divide 432 by 72, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1906.0
The remainder is 0 after subtracting 432 from 432.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 72

Let's proceed to step 7:
The number 72 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 19060.0
If we take 0 away from 7, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 72

Let's proceed to step 8:
71 divided by 72 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 190600.0
Subtract 0 from 71 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
72 can be fit into 710 9 times, resulting in a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 190600.9
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
620 divided by 72 is 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 190600.98
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
72 goes into 440 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 190600.986
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
72 goes into 80 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 190600.9861
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 72, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 190600.98611
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 190600.98611 and a remainder of 8e-06.
