We're dividing 499252 by 51 
The aim is to understand the frequency of 51 in 499252.

Step 1:
51 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 51

Advancing to step 2:
51 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 51

Going ahead to step 3:
51 goes into 499 9 times with a remainder of 40.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 459 from 499 and we're left with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 51

Moving on to step 4:
402 divided by 51 is 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 45 after subtracting 357 from 402.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 51

Moving on to step 5:
The number 51 fits into 455 8 times, leaving a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 978.0
If we take 408 away from 455, we end up with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 51

On to step 6:
If we divide 472 by 51, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 9789.0
The remainder is 13 after subtracting 459 from 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 51, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 9789.2
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
When dividing 280 by 51, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9789.25
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
51 goes into 250 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 9789.254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
460 divided by 51 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9789.2549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 9789.2549
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 51 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 9789.254901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
490 divided by 51 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 9789.2549019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
When dividing 310 by 51, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 9789.25490196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 9789.25490196 and a remainder of 4e-09.
