68557256 ÷ 528 
The aim is to understand the frequency of 528 in 68557256.

Let's proceed to step 1:
The number 528 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 528

Moving on to step 2:
528 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 528

Going ahead to step 3:
528 can be fit into 685 1 times, resulting in a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 528 from 685, we get 157.
Take the next digit (5) from the dividend and append it to 157, then repeat: 1575 / 528

Step 4:
The number 528 fits into 1575 2 times, leaving a remainder of 519.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1056 from 1575, we get 519.
Append the next digit (7) from the dividend to 519 and continue with: 5197 / 528

Going ahead to step 5:
528 goes into 5197 9 times with a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtract 4752 from 5197 to get 445.
Append the next digit (2) from the dividend to 445 and continue with: 4452 / 528

Advancing to step 6:
528 goes into 4452 8 times with a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 1298.0
The remainder is 228 after subtracting 4224 from 4452.
Grab the next digit (5) from the dividend, add it to 228, then carry on: 2285 / 528

Let's proceed to step 7:
When dividing 2285 by 528, we get 4 with a remainder of 173.
The number 4 becomes the next digit in our result. 
Result so far: 12984.0
Subtract 2112 from 2285 to get 173.
Include the next digit (6) from the dividend after 173, then repeat: 1736 / 528

Going ahead to step 8:
When dividing 1736 by 528, we get 3 with a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 129843.0
The remainder is 152 after subtracting 1584 from 1736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 9:
If we divide 1520 by 528, we get 2 and a remainder of 464.
The next digit of our result is 2. 
Result so far: 129843.2
If we subtract 1056 from 1520, 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 10:
The number 528 fits into 4640 8 times, leaving a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 129843.28
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.

On to step 11:
The number 528 fits into 4160 7 times, leaving a remainder of 464.
The next digit of our result is 7. 
Result so far: 129843.287
Subtract 3696 from 4160 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.

Going ahead to step 12:
528 can be fit into 4640 8 times, resulting in a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 129843.2878
Subtracting 4224 from 4640 leaves us 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.

Advancing to step 13:
528 can be fit into 4160 7 times, resulting in a remainder of 464.
The number 7 becomes the next digit in our result. 
Result so far: 129843.28787
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.

Going ahead to step 14:
528 goes into 4640 8 times with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 129843.287878
Subtract 4224 from 4640 to 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.

On to step 15:
If we divide 4160 by 528, we get 7 and a remainder of 464.
Record the quotient 7 as the next digit in the result. 
Result so far: 129843.2878787
Deduct 3696 from 4160 and we're left 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.

Advancing to step 16:
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: 129843.28787878
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.

The final outcome is 129843.28787878, with a leftover of 4.16e-07.
