We look at the division of 69604749 by 72 
The aim is to understand the frequency of 72 in 69604749.

Moving on to step 1:
6 divided by 72 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 72

Advancing to step 2:
When dividing 69 by 72, we get 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 72

Advancing to step 3:
72 can be fit into 696 9 times, resulting in a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 648 from 696 and we're left with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 72

On to step 4:
480 divided by 72 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 432 away from 480, we end up with 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 72

Going ahead to step 5:
72 goes into 484 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 966.0
Subtracting 432 from 484 leaves us with 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 72

Moving on to step 6:
72 goes into 527 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 9667.0
Subtracting 504 from 527 leaves us with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 72

Advancing to step 7:
72 can be fit into 234 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 96673.0
Deduct 216 from 234 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 72

Going ahead to step 8:
72 goes into 189 2 times with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 966732.0
Subtracting 144 from 189 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
72 can be fit into 450 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 966732.6
Subtracting 432 from 450 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
72 goes into 180 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 966732.62
Deduct 144 from 180 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
If we divide 360 by 72, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 966732.625
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 72 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 966732.625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
If we divide 0 by 72, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 966732.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 966732.625, with a leftover of 0.0.
