129902 divided by 51 
The aim is to understand the frequency of 51 in 129902.

Let's proceed to step 1:
51 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 51

Moving on to step 2:
51 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 51

Going ahead to step 3:
129 divided by 51 is 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 102 from 129 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 51

Let's proceed to step 4:
51 goes into 279 5 times with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 24 after subtracting 255 from 279.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 51

Let's proceed to step 5:
240 divided by 51 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 254.0
The remainder is 36 after subtracting 204 from 240.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 51

Advancing to step 6:
If we divide 362 by 51, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 2547.0
The remainder is 5 after subtracting 357 from 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 51 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 2547.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 2547.09
Subtract 459 from 500 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
51 goes into 410 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2547.098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
51 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2547.098
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
51 goes into 200 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 2547.09803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2547.098039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
When dividing 110 by 51, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2547.0980392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
When dividing 80 by 51, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 2547.09803921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 2547.09803921 with a remaining 2.9e-08.
