We're dividing 15323941 by 72 
The aim is to understand the frequency of 72 in 15323941.

Step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 72

Step 2:
72 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 72

Advancing to step 3:
72 goes into 153 2 times with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 144 from 153 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 72

On to step 4:
92 divided by 72 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 72 from 92, we get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 72

Moving on to step 5:
72 goes into 203 2 times with a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 212.0
The remainder is 59 after subtracting 144 from 203.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 72

Going ahead to step 6:
599 divided by 72 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 2128.0
If we subtract 576 from 599, we get 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 72

Let's proceed to step 7:
The number 72 fits into 234 3 times, leaving a remainder of 18.
The next digit of our result is 3. 
Result so far: 21283.0
If we take 216 away from 234, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 72

Moving on to step 8:
The number 72 fits into 181 2 times, leaving a remainder of 37.
The next digit of our result is 2. 
Result so far: 212832.0
The remainder is 37 after subtracting 144 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
The number 72 fits into 370 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 212832.5
Deduct 360 from 370 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
72 can be fit into 100 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 212832.51
Deduct 72 from 100 and we're left 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 11:
The number 72 fits into 280 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 212832.513
Deduct 216 from 280 and we're left 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.

Going ahead to step 12:
When dividing 640 by 72, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 212832.5138
Subtract 576 from 640 to 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.

Advancing to step 13:
640 divided by 72 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 212832.51388
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.

In conclusion, the division gives 212832.51388 with a balance of 6.4e-05.
