We're dividing 22365870 by 72 
The aim is to understand the frequency of 72 in 22365870.

Let's proceed to step 1:
The number 72 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 72

Advancing to step 2:
72 can be fit into 22 0 times, resulting in a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 72

Advancing to step 3:
If we divide 223 by 72, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 216 from 223 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 72

Moving on to step 4:
If we divide 76 by 72, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 72 from 76 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 72

Step 5:
72 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 310.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 72

Let's proceed to step 6:
If we divide 458 by 72, we get 6 and a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 3106.0
Subtract 432 from 458 to get 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 72

Advancing to step 7:
267 divided by 72 is 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 31063.0
Subtract 216 from 267 to get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 72

Going ahead to step 8:
72 goes into 510 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 310637.0
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 72, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 310637.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 72, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 310637.08
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
The number 72 fits into 240 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 310637.083
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 72, we get 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 310637.0833
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 310637.0833 with a balance of 0.00024.
