We divide 72012272 by 528
The aim is to understand the frequency of 528 in 72012272.

Going ahead to step 1:
The number 528 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 528

Moving on to step 2:
528 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 528

Advancing to step 3:
When dividing 720 by 528, we get 1 with a remainder of 192.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 528 from 720 and we're left with 192.
Fetch the next digit (1) from the dividend, attach it to 192 and continue: 1921 / 528

Going ahead to step 4:
528 goes into 1921 3 times with a remainder of 337.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1584 from 1921 leaves us with 337.
Include the next digit (2) from the dividend after 337, then repeat: 3372 / 528

Step 5:
If we divide 3372 by 528, we get 6 and a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtracting 3168 from 3372 leaves us with 204.
Include the next digit (2) from the dividend after 204, then repeat: 2042 / 528

Going ahead to step 6:
2042 divided by 528 is 3 with a remainder of 458.
Record the quotient 3 as the next digit in the result. 
Result so far: 1363.0
Deduct 1584 from 2042 and we're left with 458.
Include the next digit (7) from the dividend after 458, then repeat: 4587 / 528

Moving on to step 7:
528 can be fit into 4587 8 times, resulting in a remainder of 363.
The number 8 becomes the next digit in our result. 
Result so far: 13638.0
Subtracting 4224 from 4587 leaves us with 363.
Take the next digit (2) from the dividend and append it to 363, then repeat: 3632 / 528

Step 8:
3632 divided by 528 is 6 with a remainder of 464.
Record the quotient 6 as the next digit in the result. 
Result so far: 136386.0
Subtract 3168 from 3632 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 9:
528 goes into 4640 8 times with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 136386.8
If we take 4224 away from 4640, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 10:
528 can be fit into 4160 7 times, resulting in a remainder of 464.
Record the quotient 7 as the next digit in the result. 
Result so far: 136386.87
If we subtract 3696 from 4160, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 11:
When dividing 4640 by 528, we get 8 with a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 136386.878
If we subtract 4224 from 4640, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 12:
528 can be fit into 4160 7 times, resulting in a remainder of 464.
The next digit of our result is 7. 
Result so far: 136386.8787
If we subtract 3696 from 4160, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
528 goes into 4640 8 times with a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 136386.87878
If we take 4224 away from 4640, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
4160 divided by 528 is 7 with a remainder of 464.
Write down 7 as next digit of the result. 
Result so far: 136386.878787
The remainder is 464 after subtracting 3696 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 15:
When dividing 4640 by 528, we get 8 with a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 136386.8787878
The remainder is 416 after subtracting 4224 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 16:
The number 528 fits into 4160 7 times, leaving a remainder of 464.
The next digit of our result is 7. 
Result so far: 136386.87878787
If we take 3696 away from 4160, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

After the division, we end up with 136386.87878787 and a remainder of 4.64e-07.
