We look at the division of 72754434 by 524 
The aim is to understand the frequency of 524 in 72754434.

Going ahead to step 1:
If we divide 7 by 524, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 524

Moving on to step 2:
If we divide 72 by 524, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 524

On to step 3:
If we divide 727 by 524, we get 1 and a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 524 from 727 leaves us with 203.
Fetch the next digit (5) from the dividend, attach it to 203 and continue: 2035 / 524

Step 4:
If we divide 2035 by 524, we get 3 and a remainder of 463.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1572 from 2035 leaves us with 463.
Take the next digit (4) from the dividend and append it to 463, then repeat: 4634 / 524

Let's proceed to step 5:
524 goes into 4634 8 times with a remainder of 442.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 4192 from 4634, we get 442.
Include the next digit (4) from the dividend after 442, then repeat: 4424 / 524

Moving on to step 6:
524 can be fit into 4424 8 times, resulting in a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 1388.0
Subtract 4192 from 4424 to get 232.
Take the next digit (3) from the dividend and append it to 232, then repeat: 2323 / 524

Going ahead to step 7:
2323 divided by 524 is 4 with a remainder of 227.
Put 4 as the next digit of the answer. 
Result so far: 13884.0
If we subtract 2096 from 2323, we get 227.
Include the next digit (4) from the dividend after 227, then repeat: 2274 / 524

Going ahead to step 8:
2274 divided by 524 is 4 with a remainder of 178.
Put 4 as the next digit of the answer. 
Result so far: 138844.0
If we take 2096 away from 2274, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 9:
When dividing 1780 by 524, we get 3 with a remainder of 208.
The number 3 becomes the next digit in our result. 
Result so far: 138844.3
Deduct 1572 from 1780 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
524 goes into 2080 3 times with a remainder of 508.
Write down 3 as next digit of the result. 
Result so far: 138844.33
The remainder is 508 after subtracting 1572 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

In conclusion, the division gives 138844.33 with a balance of 0.508.
