We look at the division of 102029 by 51 
The aim is to understand the frequency of 51 in 102029.

Let's proceed to step 1:
1 divided by 51 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 51

Advancing to step 2:
51 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 51

Advancing to step 3:
When dividing 102 by 51, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 102 from 102.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 51

Advancing to step 4:
0 divided by 51 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 51

Moving on to step 5:
When dividing 2 by 51, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 200.0
If we subtract 0 from 2, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 51

Step 6:
The number 51 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 2000.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
51 goes into 290 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 2000.5
Deduct 255 from 290 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2000.56
If we take 306 away from 350, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
51 goes into 440 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2000.568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
51 can be fit into 320 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 2000.5686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
51 can be fit into 140 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2000.56862
Subtract 102 from 140 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
380 divided by 51 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 2000.568627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 2000.5686274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2000.56862745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 2000.56862745 with a remainder of 5e-09.
