We divide 99975529 by 528
The aim is to understand the frequency of 528 in 99975529.

Advancing to step 1:
When dividing 9 by 528, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 528

Going ahead to step 2:
If we divide 99 by 528, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 528

Going ahead to step 3:
The number 528 fits into 999 1 times, leaving a remainder of 471.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 528 from 999, we get 471.
Include the next digit (7) from the dividend after 471, then repeat: 4717 / 528

On to step 4:
528 can be fit into 4717 8 times, resulting in a remainder of 493.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 4224 from 4717 to get 493.
Include the next digit (5) from the dividend after 493, then repeat: 4935 / 528

Going ahead to step 5:
528 can be fit into 4935 9 times, resulting in a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 189.0
The remainder is 183 after subtracting 4752 from 4935.
Take the next digit (5) from the dividend and append it to 183, then repeat: 1835 / 528

On to step 6:
The number 528 fits into 1835 3 times, leaving a remainder of 251.
Put 3 as the next digit of the answer. 
Result so far: 1893.0
Subtracting 1584 from 1835 leaves us with 251.
Bring next digit (2) of the dividend behind the 251 and repeat the process: 2512 / 528

Moving on to step 7:
528 can be fit into 2512 4 times, resulting in a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 18934.0
Deduct 2112 from 2512 and we're left with 400.
Grab the next digit (9) from the dividend, add it to 400, then carry on: 4009 / 528

Step 8:
528 goes into 4009 7 times with a remainder of 313.
Record the quotient 7 as the next digit in the result. 
Result so far: 189347.0
Subtract 3696 from 4009 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 9:
When dividing 3130 by 528, we get 5 with a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 189347.5
If we subtract 2640 from 3130, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
528 goes into 4900 9 times with a remainder of 148.
Write down 9 as next digit of the result. 
Result so far: 189347.59
The remainder is 148 after subtracting 4752 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 11:
528 can be fit into 1480 2 times, resulting in a remainder of 424.
Use 2 as the next digit of our solution. 
Result so far: 189347.592
Deduct 1056 from 1480 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 12:
528 goes into 4240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 189347.5928
Deduct 4224 from 4240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
528 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 189347.5928
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
528 goes into 1600 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 189347.592803
Subtracting 1584 from 1600 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
When dividing 160 by 528, we get 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 189347.592803
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 16:
If we divide 1600 by 528, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 189347.59280303
If we subtract 1584 from 1600, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 189347.59280303 with a balance of 1.6e-08.
