We look at the division of 492238 by 51 
The aim is to understand the frequency of 51 in 492238.

Step 1:
4 divided by 51 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 51

Step 2:
The number 51 fits into 49 0 times, leaving a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 51

Moving on to step 3:
492 divided by 51 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 459 away from 492, we end up with 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 51

Going ahead to step 4:
The number 51 fits into 332 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 306 away from 332, we end up with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 51

Step 5:
51 can be fit into 263 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 965.0
The remainder is 8 after subtracting 255 from 263.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 51

Moving on to step 6:
The number 51 fits into 88 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 9651.0
Subtracting 51 from 88 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
If we divide 370 by 51, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 9651.7
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
130 divided by 51 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 9651.72
If we subtract 102 from 130, we 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.

Let's proceed to step 9:
280 divided by 51 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9651.725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
If we divide 250 by 51, we get 4 and a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 9651.7254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
51 goes into 460 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9651.72549
The remainder is 1 after subtracting 459 from 460.
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 12:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9651.72549
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
51 goes into 100 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 9651.7254901
Deduct 51 from 100 and we're left with 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 14:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 9651.72549019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 9651.72549019 and a remainder of 3.1e-08.
