We look at the division of 44512572 by 72 
The aim is to understand the frequency of 72 in 44512572.

Going ahead to step 1:
4 divided by 72 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 72

Let's proceed to step 2:
When dividing 44 by 72, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 72

Let's proceed to step 3:
The number 72 fits into 445 6 times, leaving a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 432 from 445 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 72

Going ahead to step 4:
72 goes into 131 1 times with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we take 72 away from 131, we end up with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 72

Let's proceed to step 5:
592 divided by 72 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 618.0
Deduct 576 from 592 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 72

Going ahead to step 6:
If we divide 165 by 72, we get 2 and a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 6182.0
Subtracting 144 from 165 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 72

Going ahead to step 7:
217 divided by 72 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 61823.0
The remainder is 1 after subtracting 216 from 217.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 72

Advancing to step 8:
12 divided by 72 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 618230.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
72 can be fit into 120 1 times, resulting in a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 618230.1
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 72 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 618230.16
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
480 divided by 72 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 618230.166
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 618230.166 with a balance of 0.0048.
