30024928 ÷ 505 
The aim is to understand the frequency of 505 in 30024928.

Step 1:
If we divide 3 by 505, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 505

Step 2:
The number 505 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 505

Moving on to step 3:
300 divided by 505 is 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 300 after subtracting 0 from 300.
Bring next digit (2) of the dividend behind the 300 and repeat the process: 3002 / 505

Let's proceed to step 4:
When dividing 3002 by 505, we get 5 with a remainder of 477.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 2525 from 3002, we get 477.
Append the next digit (4) from the dividend to 477 and continue with: 4774 / 505

Going ahead to step 5:
The number 505 fits into 4774 9 times, leaving a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we take 4545 away from 4774, we end up with 229.
Append the next digit (9) from the dividend to 229 and continue with: 2299 / 505

Let's proceed to step 6:
When dividing 2299 by 505, we get 4 with a remainder of 279.
Put 4 as the next digit of the answer. 
Result so far: 594.0
The remainder is 279 after subtracting 2020 from 2299.
Append the next digit (2) from the dividend to 279 and continue with: 2792 / 505

Let's proceed to step 7:
505 goes into 2792 5 times with a remainder of 267.
The next digit of our result is 5. 
Result so far: 5945.0
Subtract 2525 from 2792 to get 267.
Fetch the next digit (8) from the dividend, attach it to 267 and continue: 2678 / 505

Step 8:
505 goes into 2678 5 times with a remainder of 153.
Put 5 as the next digit of the answer. 
Result so far: 59455.0
If we take 2525 away from 2678, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 9:
1530 divided by 505 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 59455.3
If we subtract 1515 from 1530, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
If we divide 150 by 505, we get 0 and a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 59455.3
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
505 goes into 1500 2 times with a remainder of 490.
Write down 2 as next digit of the result. 
Result so far: 59455.302
Deduct 1010 from 1500 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 12:
The number 505 fits into 4900 9 times, leaving a remainder of 355.
Write down 9 as next digit of the result. 
Result so far: 59455.3029
The remainder is 355 after subtracting 4545 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 13:
505 can be fit into 3550 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 59455.30297
If we subtract 3535 from 3550, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
When dividing 150 by 505, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 59455.30297
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
505 can be fit into 1500 2 times, resulting in a remainder of 490.
The number 2 becomes the next digit in our result. 
Result so far: 59455.3029702
Subtract 1010 from 1500 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 16:
505 can be fit into 4900 9 times, resulting in a remainder of 355.
Use 9 as the next digit of our solution. 
Result so far: 59455.30297029
The remainder is 355 after subtracting 4545 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Our division results in 59455.30297029 with a remaining 3.55e-07.
