Let's divide 95350231 by 509
The aim is to understand the frequency of 509 in 95350231.

Advancing to step 1:
509 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 509

Moving on to step 2:
509 can be fit into 95 0 times, resulting in a remainder of 95.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 95, we end up with 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 509

Going ahead to step 3:
509 can be fit into 953 1 times, resulting in a remainder of 444.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 509 from 953 leaves us with 444.
Bring next digit (5) of the dividend behind the 444 and repeat the process: 4445 / 509

Moving on to step 4:
When dividing 4445 by 509, we get 8 with a remainder of 373.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 4072 from 4445 to get 373.
Append the next digit (0) from the dividend to 373 and continue with: 3730 / 509

Advancing to step 5:
3730 divided by 509 is 7 with a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtract 3563 from 3730 to get 167.
Append the next digit (2) from the dividend to 167 and continue with: 1672 / 509

Step 6:
509 can be fit into 1672 3 times, resulting in a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 1873.0
Subtract 1527 from 1672 to get 145.
Grab the next digit (3) from the dividend, add it to 145, then carry on: 1453 / 509

Going ahead to step 7:
The number 509 fits into 1453 2 times, leaving a remainder of 435.
The next digit of our result is 2. 
Result so far: 18732.0
The remainder is 435 after subtracting 1018 from 1453.
Bring next digit (1) of the dividend behind the 435 and repeat the process: 4351 / 509

Moving on to step 8:
If we divide 4351 by 509, we get 8 and a remainder of 279.
The next digit of our result is 8. 
Result so far: 187328.0
Deduct 4072 from 4351 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 9:
When dividing 2790 by 509, we get 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 187328.5
Subtracting 2545 from 2790 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 10:
When dividing 2450 by 509, we get 4 with a remainder of 414.
Write down 4 as next digit of the result. 
Result so far: 187328.54
If we take 2036 away from 2450, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 11:
The number 509 fits into 4140 8 times, leaving a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 187328.548
The remainder is 68 after subtracting 4072 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
509 goes into 680 1 times with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 187328.5481
Deduct 509 from 680 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 13:
When dividing 1710 by 509, we get 3 with a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 187328.54813
The remainder is 183 after subtracting 1527 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 14:
When dividing 1830 by 509, we get 3 with a remainder of 303.
Use 3 as the next digit of our solution. 
Result so far: 187328.548133
Subtract 1527 from 1830 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

After the division, we end up with 187328.548133 and a remainder of 3.03e-05.
