14692666 ÷ 520 
The aim is to understand the frequency of 520 in 14692666.

Let's proceed to step 1:
When dividing 1 by 520, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 520

Moving on to step 2:
If we divide 14 by 520, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 520

Step 3:
146 divided by 520 is 0 with a remainder of 146.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 146 to get 146.
Take the next digit (9) from the dividend and append it to 146, then repeat: 1469 / 520

Going ahead to step 4:
When dividing 1469 by 520, we get 2 with a remainder of 429.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1040 from 1469 leaves us with 429.
Bring next digit (2) of the dividend behind the 429 and repeat the process: 4292 / 520

Let's proceed to step 5:
520 goes into 4292 8 times with a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 132 after subtracting 4160 from 4292.
Bring next digit (6) of the dividend behind the 132 and repeat the process: 1326 / 520

Let's proceed to step 6:
The number 520 fits into 1326 2 times, leaving a remainder of 286.
The next digit of our result is 2. 
Result so far: 282.0
Subtracting 1040 from 1326 leaves us with 286.
Take the next digit (6) from the dividend and append it to 286, then repeat: 2866 / 520

Going ahead to step 7:
2866 divided by 520 is 5 with a remainder of 266.
Record the quotient 5 as the next digit in the result. 
Result so far: 2825.0
The remainder is 266 after subtracting 2600 from 2866.
Append the next digit (6) from the dividend to 266 and continue with: 2666 / 520

Let's proceed to step 8:
When dividing 2666 by 520, we get 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 28255.0
Subtracting 2600 from 2666 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 520 fits into 660 1 times, leaving a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 28255.1
Deduct 520 from 660 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
The number 520 fits into 1400 2 times, leaving a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 28255.12
Subtracting 1040 from 1400 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
If we divide 3600 by 520, we get 6 and a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 28255.126
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
When dividing 4800 by 520, we get 9 with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 28255.1269
The remainder is 120 after subtracting 4680 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 28255.12692
If we take 1040 away from 1200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
520 goes into 1600 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 28255.126923
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
520 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 28255.126923
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 16:
If we divide 4000 by 520, we get 7 and a remainder of 360.
The next digit of our result is 7. 
Result so far: 28255.12692307
Deduct 3640 from 4000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 28255.12692307 with a remainder of 3.6e-07.
