We're dividing 20089342 by 521 
The aim is to understand the frequency of 521 in 20089342.

Moving on to step 1:
521 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 521

On to step 2:
521 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 521

Moving on to step 3:
When dividing 200 by 521, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 200 after subtracting 0 from 200.
Append the next digit (8) from the dividend to 200 and continue with: 2008 / 521

On to step 4:
When dividing 2008 by 521, we get 3 with a remainder of 445.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 445 after subtracting 1563 from 2008.
Append the next digit (9) from the dividend to 445 and continue with: 4459 / 521

Moving on to step 5:
When dividing 4459 by 521, we get 8 with a remainder of 291.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtract 4168 from 4459 to get 291.
Fetch the next digit (3) from the dividend, attach it to 291 and continue: 2913 / 521

On to step 6:
The number 521 fits into 2913 5 times, leaving a remainder of 308.
The next digit of our result is 5. 
Result so far: 385.0
If we subtract 2605 from 2913, we get 308.
Bring next digit (4) of the dividend behind the 308 and repeat the process: 3084 / 521

On to step 7:
521 can be fit into 3084 5 times, resulting in a remainder of 479.
Write down 5 as next digit of the result. 
Result so far: 3855.0
If we subtract 2605 from 3084, we get 479.
Bring next digit (2) of the dividend behind the 479 and repeat the process: 4792 / 521

Step 8:
The number 521 fits into 4792 9 times, leaving a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 38559.0
The remainder is 103 after subtracting 4689 from 4792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
If we divide 1030 by 521, we get 1 and a remainder of 509.
The next digit of our result is 1. 
Result so far: 38559.1
Subtract 521 from 1030 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 10:
5090 divided by 521 is 9 with a remainder of 401.
Put 9 as the next digit of the answer. 
Result so far: 38559.19
If we subtract 4689 from 5090, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 11:
4010 divided by 521 is 7 with a remainder of 363.
Put 7 as the next digit of the answer. 
Result so far: 38559.197
Deduct 3647 from 4010 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 12:
521 can be fit into 3630 6 times, resulting in a remainder of 504.
Write down 6 as next digit of the result. 
Result so far: 38559.1976
The remainder is 504 after subtracting 3126 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 13:
5040 divided by 521 is 9 with a remainder of 351.
The next digit of our result is 9. 
Result so far: 38559.19769
If we take 4689 away from 5040, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 14:
521 can be fit into 3510 6 times, resulting in a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 38559.197696
Subtract 3126 from 3510 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
When dividing 3840 by 521, we get 7 with a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 38559.1976967
If we take 3647 away from 3840, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 16:
521 goes into 1930 3 times with a remainder of 367.
The next digit of our result is 3. 
Result so far: 38559.19769673
If we take 1563 away from 1930, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The quotient of the division is 38559.19769673, and the remainder is 3.67e-07.
