We look at the division of 20983319 by 528 
The aim is to understand the frequency of 528 in 20983319.

Going ahead to step 1:
When dividing 2 by 528, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 528

On to step 2:
528 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 528

Going ahead to step 3:
528 can be fit into 209 0 times, resulting in a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Include the next digit (8) from the dividend after 209, then repeat: 2098 / 528

Let's proceed to step 4:
The number 528 fits into 2098 3 times, leaving a remainder of 514.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 514 after subtracting 1584 from 2098.
Bring next digit (3) of the dividend behind the 514 and repeat the process: 5143 / 528

On to step 5:
528 goes into 5143 9 times with a remainder of 391.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 4752 from 5143, we get 391.
Append the next digit (3) from the dividend to 391 and continue with: 3913 / 528

Let's proceed to step 6:
528 goes into 3913 7 times with a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtracting 3696 from 3913 leaves us with 217.
Append the next digit (1) from the dividend to 217 and continue with: 2171 / 528

On to step 7:
2171 divided by 528 is 4 with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 3974.0
Subtracting 2112 from 2171 leaves us with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 528

Let's proceed to step 8:
When dividing 599 by 528, we get 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 39741.0
If we subtract 528 from 599, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
The number 528 fits into 710 1 times, leaving a remainder of 182.
Write down 1 as next digit of the result. 
Result so far: 39741.1
The remainder is 182 after subtracting 528 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
The number 528 fits into 1820 3 times, leaving a remainder of 236.
The next digit of our result is 3. 
Result so far: 39741.13
Subtracting 1584 from 1820 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
528 can be fit into 2360 4 times, resulting in a remainder of 248.
The next digit of our result is 4. 
Result so far: 39741.134
Deduct 2112 from 2360 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 12:
The number 528 fits into 2480 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 39741.1344
If we subtract 2112 from 2480, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 39741.1344, with a leftover of 0.00368.
