We divide 35190261 by 509
The aim is to understand the frequency of 509 in 35190261.

Let's proceed to step 1:
The number 509 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 509

Let's proceed to step 2:
35 divided by 509 is 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 509

On to step 3:
509 goes into 351 0 times with a remainder of 351.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 351, we end up with 351.
Append the next digit (9) from the dividend to 351 and continue with: 3519 / 509

Advancing to step 4:
3519 divided by 509 is 6 with a remainder of 465.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 3054 from 3519 to get 465.
Fetch the next digit (0) from the dividend, attach it to 465 and continue: 4650 / 509

Going ahead to step 5:
4650 divided by 509 is 9 with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 4581 from 4650 and we're left with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 509

Advancing to step 6:
509 goes into 692 1 times with a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 691.0
If we subtract 509 from 692, we get 183.
Append the next digit (6) from the dividend to 183 and continue with: 1836 / 509

Step 7:
The number 509 fits into 1836 3 times, leaving a remainder of 309.
Use 3 as the next digit of our solution. 
Result so far: 6913.0
Subtracting 1527 from 1836 leaves us with 309.
Fetch the next digit (1) from the dividend, attach it to 309 and continue: 3091 / 509

On to step 8:
If we divide 3091 by 509, we get 6 and a remainder of 37.
The next digit of our result is 6. 
Result so far: 69136.0
If we subtract 3054 from 3091, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
When dividing 370 by 509, we get 0 with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 69136.0
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
509 can be fit into 3700 7 times, resulting in a remainder of 137.
The next digit of our result is 7. 
Result so far: 69136.07
Deduct 3563 from 3700 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 11:
509 can be fit into 1370 2 times, resulting in a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 69136.072
If we take 1018 away from 1370, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 12:
The number 509 fits into 3520 6 times, leaving a remainder of 466.
Write down 6 as next digit of the result. 
Result so far: 69136.0726
Deduct 3054 from 3520 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 13:
509 can be fit into 4660 9 times, resulting in a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 69136.07269
Subtracting 4581 from 4660 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 14:
When dividing 790 by 509, we get 1 with a remainder of 281.
The number 1 becomes the next digit in our result. 
Result so far: 69136.072691
If we subtract 509 from 790, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 15:
When dividing 2810 by 509, we get 5 with a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 69136.0726915
The remainder is 265 after subtracting 2545 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 16:
If we divide 2650 by 509, we get 5 and a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 69136.07269155
Deduct 2545 from 2650 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 69136.07269155, with a leftover of 1.05e-07.
