We divide 25518383 by 510
The aim is to understand the frequency of 510 in 25518383.

Moving on to step 1:
510 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 510

Moving on to step 2:
When dividing 25 by 510, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 510

Step 3:
510 goes into 255 0 times with a remainder of 255.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 255 leaves us with 255.
Append the next digit (1) from the dividend to 255 and continue with: 2551 / 510

Going ahead to step 4:
When dividing 2551 by 510, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 2550 away from 2551, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 510

Advancing to step 5:
If we divide 18 by 510, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 510

Going ahead to step 6:
When dividing 183 by 510, we get 0 with a remainder of 183.
Use 0 as the next digit of our solution. 
Result so far: 500.0
The remainder is 183 after subtracting 0 from 183.
Include the next digit (8) from the dividend after 183, then repeat: 1838 / 510

On to step 7:
When dividing 1838 by 510, we get 3 with a remainder of 308.
Write down 3 as next digit of the result. 
Result so far: 5003.0
If we subtract 1530 from 1838, we get 308.
Bring next digit (3) of the dividend behind the 308 and repeat the process: 3083 / 510

Step 8:
510 goes into 3083 6 times with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 50036.0
If we take 3060 away from 3083, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
510 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 50036.0
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
When dividing 2300 by 510, we get 4 with a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 50036.04
Subtracting 2040 from 2300 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.

Step 11:
510 can be fit into 2600 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 50036.045
Subtract 2550 from 2600 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
When dividing 500 by 510, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 50036.045
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
When dividing 5000 by 510, we get 9 with a remainder of 410.
Record the quotient 9 as the next digit in the result. 
Result so far: 50036.04509
Subtracting 4590 from 5000 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.

Let's proceed to step 14:
510 goes into 4100 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 50036.045098
The remainder is 20 after subtracting 4080 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
If we divide 200 by 510, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 50036.045098
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 16:
If we divide 2000 by 510, we get 3 and a remainder of 470.
Record the quotient 3 as the next digit in the result. 
Result so far: 50036.04509803
Subtract 1530 from 2000 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final outcome is 50036.04509803, with a leftover of 4.7e-07.
