We look at the division of 35690453 by 528 
The aim is to understand the frequency of 528 in 35690453.

Let's proceed to step 1:
The number 528 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 528

Going ahead to step 2:
35 divided by 528 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 528

Let's proceed to step 3:
When dividing 356 by 528, we get 0 with a remainder of 356.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 356, we get 356.
Include the next digit (9) from the dividend after 356, then repeat: 3569 / 528

Going ahead to step 4:
If we divide 3569 by 528, we get 6 and a remainder of 401.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 401 after subtracting 3168 from 3569.
Grab the next digit (0) from the dividend, add it to 401, then carry on: 4010 / 528

Advancing to step 5:
528 can be fit into 4010 7 times, resulting in a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we take 3696 away from 4010, we end up with 314.
Take the next digit (4) from the dividend and append it to 314, then repeat: 3144 / 528

Step 6:
The number 528 fits into 3144 5 times, leaving a remainder of 504.
Put 5 as the next digit of the answer. 
Result so far: 675.0
Subtract 2640 from 3144 to get 504.
Include the next digit (5) from the dividend after 504, then repeat: 5045 / 528

Advancing to step 7:
If we divide 5045 by 528, we get 9 and a remainder of 293.
The number 9 becomes the next digit in our result. 
Result so far: 6759.0
The remainder is 293 after subtracting 4752 from 5045.
Fetch the next digit (3) from the dividend, attach it to 293 and continue: 2933 / 528

Moving on to step 8:
528 goes into 2933 5 times with a remainder of 293.
Use 5 as the next digit of our solution. 
Result so far: 67595.0
If we take 2640 away from 2933, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
If we divide 2930 by 528, we get 5 and a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 67595.5
Subtract 2640 from 2930 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
If we divide 2900 by 528, we get 5 and a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 67595.55
Deduct 2640 from 2900 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 67595.55 with a remainder of 0.26.
