Let's divide 81516532 by 528
The aim is to understand the frequency of 528 in 81516532.

Advancing to step 1:
8 divided by 528 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 528

Let's proceed to step 2:
When dividing 81 by 528, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 528

Going ahead to step 3:
528 can be fit into 815 1 times, resulting in a remainder of 287.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 528 from 815 and we're left with 287.
Take the next digit (1) from the dividend and append it to 287, then repeat: 2871 / 528

Let's proceed to step 4:
528 can be fit into 2871 5 times, resulting in a remainder of 231.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2640 from 2871 to get 231.
Bring next digit (6) of the dividend behind the 231 and repeat the process: 2316 / 528

Let's proceed to step 5:
2316 divided by 528 is 4 with a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtracting 2112 from 2316 leaves us with 204.
Append the next digit (5) from the dividend to 204 and continue with: 2045 / 528

Step 6:
528 can be fit into 2045 3 times, resulting in a remainder of 461.
The number 3 becomes the next digit in our result. 
Result so far: 1543.0
If we take 1584 away from 2045, we end up with 461.
Include the next digit (3) from the dividend after 461, then repeat: 4613 / 528

Moving on to step 7:
If we divide 4613 by 528, we get 8 and a remainder of 389.
Write down 8 as next digit of the result. 
Result so far: 15438.0
If we take 4224 away from 4613, we end up with 389.
Take the next digit (2) from the dividend and append it to 389, then repeat: 3892 / 528

Let's proceed to step 8:
528 can be fit into 3892 7 times, resulting in a remainder of 196.
The next digit of our result is 7. 
Result so far: 154387.0
The remainder is 196 after subtracting 3696 from 3892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 9:
1960 divided by 528 is 3 with a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 154387.3
Deduct 1584 from 1960 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 10:
The number 528 fits into 3760 7 times, leaving a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 154387.37
Subtracting 3696 from 3760 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
528 goes into 640 1 times with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 154387.371
Deduct 528 from 640 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
When dividing 1120 by 528, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 154387.3712
Subtract 1056 from 1120 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
528 goes into 640 1 times with a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 154387.37121
If we take 528 away from 640, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 14:
528 can be fit into 1120 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 154387.371212
If we take 1056 away from 1120, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
640 divided by 528 is 1 with a remainder of 112.
The next digit of our result is 1. 
Result so far: 154387.3712121
The remainder is 112 after subtracting 528 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 16:
When dividing 1120 by 528, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 154387.37121212
The remainder is 64 after subtracting 1056 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 154387.37121212 and a remainder of 6.4e-08.
