We're dividing 58206131 by 509 
The aim is to understand the frequency of 509 in 58206131.

Step 1:
If we divide 5 by 509, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 509

Step 2:
509 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (2) from the dividend to 58 and continue with: 582 / 509

Step 3:
509 can be fit into 582 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 509 away from 582, we end up with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 509

Moving on to step 4:
The number 509 fits into 730 1 times, leaving a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 221 after subtracting 509 from 730.
Bring next digit (6) of the dividend behind the 221 and repeat the process: 2216 / 509

Going ahead to step 5:
509 can be fit into 2216 4 times, resulting in a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Subtracting 2036 from 2216 leaves us with 180.
Fetch the next digit (1) from the dividend, attach it to 180 and continue: 1801 / 509

Advancing to step 6:
If we divide 1801 by 509, we get 3 and a remainder of 274.
The number 3 becomes the next digit in our result. 
Result so far: 1143.0
If we take 1527 away from 1801, we end up with 274.
Include the next digit (3) from the dividend after 274, then repeat: 2743 / 509

On to step 7:
509 can be fit into 2743 5 times, resulting in a remainder of 198.
The next digit of our result is 5. 
Result so far: 11435.0
Subtract 2545 from 2743 to get 198.
Bring next digit (1) of the dividend behind the 198 and repeat the process: 1981 / 509

Advancing to step 8:
509 goes into 1981 3 times with a remainder of 454.
Record the quotient 3 as the next digit in the result. 
Result so far: 114353.0
Subtract 1527 from 1981 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 9:
509 goes into 4540 8 times with a remainder of 468.
Write down 8 as next digit of the result. 
Result so far: 114353.8
If we subtract 4072 from 4540, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 10:
509 can be fit into 4680 9 times, resulting in a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 114353.89
Subtract 4581 from 4680 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
990 divided by 509 is 1 with a remainder of 481.
The next digit of our result is 1. 
Result so far: 114353.891
If we subtract 509 from 990, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 12:
509 can be fit into 4810 9 times, resulting in a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 114353.8919
If we take 4581 away from 4810, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 13:
If we divide 2290 by 509, we get 4 and a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 114353.89194
If we take 2036 away from 2290, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 14:
The number 509 fits into 2540 4 times, leaving a remainder of 504.
The number 4 becomes the next digit in our result. 
Result so far: 114353.891944
Subtract 2036 from 2540 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final outcome is 114353.891944, with a leftover of 5.04e-05.
