18254284 ÷ 515 
The aim is to understand the frequency of 515 in 18254284.

Going ahead to step 1:
The number 515 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 515

Let's proceed to step 2:
18 divided by 515 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 515

Let's proceed to step 3:
515 can be fit into 182 0 times, resulting in a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 182 leaves us with 182.
Include the next digit (5) from the dividend after 182, then repeat: 1825 / 515

Step 4:
515 can be fit into 1825 3 times, resulting in a remainder of 280.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1545 away from 1825, we end up with 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 515

Step 5:
2804 divided by 515 is 5 with a remainder of 229.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 2575 from 2804, we get 229.
Append the next digit (2) from the dividend to 229 and continue with: 2292 / 515

Moving on to step 6:
If we divide 2292 by 515, we get 4 and a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
Deduct 2060 from 2292 and we're left with 232.
Include the next digit (8) from the dividend after 232, then repeat: 2328 / 515

Moving on to step 7:
515 goes into 2328 4 times with a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 3544.0
If we take 2060 away from 2328, we end up with 268.
Append the next digit (4) from the dividend to 268 and continue with: 2684 / 515

Moving on to step 8:
The number 515 fits into 2684 5 times, leaving a remainder of 109.
Use 5 as the next digit of our solution. 
Result so far: 35445.0
If we subtract 2575 from 2684, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
When dividing 1090 by 515, we get 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 35445.2
If we subtract 1030 from 1090, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 515, we get 1 with a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 35445.21
Subtracting 515 from 600 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
515 can be fit into 850 1 times, resulting in a remainder of 335.
Use 1 as the next digit of our solution. 
Result so far: 35445.211
Subtract 515 from 850 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final result is 35445.211 with a remainder of 0.0335.
