29535494 ÷ 509 
The aim is to understand the frequency of 509 in 29535494.

Step 1:
When dividing 2 by 509, we get 0 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.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 509

Advancing to step 2:
509 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 509

Going ahead to step 3:
If we divide 295 by 509, we get 0 and a remainder of 295.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 295 after subtracting 0 from 295.
Take the next digit (3) from the dividend and append it to 295, then repeat: 2953 / 509

Going ahead to step 4:
The number 509 fits into 2953 5 times, leaving a remainder of 408.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2545 from 2953 and we're left with 408.
Fetch the next digit (5) from the dividend, attach it to 408 and continue: 4085 / 509

Advancing to step 5:
509 can be fit into 4085 8 times, resulting in a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 4072 from 4085 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 509

Step 6:
134 divided by 509 is 0 with a remainder of 134.
The next digit of our result is 0. 
Result so far: 580.0
If we take 0 away from 134, we end up with 134.
Bring next digit (9) of the dividend behind the 134 and repeat the process: 1349 / 509

Moving on to step 7:
When dividing 1349 by 509, we get 2 with a remainder of 331.
Use 2 as the next digit of our solution. 
Result so far: 5802.0
The remainder is 331 after subtracting 1018 from 1349.
Append the next digit (4) from the dividend to 331 and continue with: 3314 / 509

Step 8:
509 can be fit into 3314 6 times, resulting in a remainder of 260.
The next digit of our result is 6. 
Result so far: 58026.0
Subtracting 3054 from 3314 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
If we divide 2600 by 509, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 58026.5
Subtracting 2545 from 2600 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
The number 509 fits into 550 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 58026.51
If we take 509 away from 550, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
509 can be fit into 410 0 times, resulting in a remainder of 410.
The next digit of our result is 0. 
Result so far: 58026.51
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 12:
509 goes into 4100 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 58026.5108
Deduct 4072 from 4100 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
509 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 58026.5108
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 14:
509 goes into 2800 5 times with a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 58026.510805
The remainder is 255 after subtracting 2545 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 15:
509 can be fit into 2550 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 58026.5108055
Subtract 2545 from 2550 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 58026.5108055 and a remainder of 5e-08.
