We look at the division of 137534 by 51 
The aim is to understand the frequency of 51 in 137534.

Advancing to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 51

Advancing to step 2:
When dividing 13 by 51, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 51

Advancing to step 3:
137 divided by 51 is 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 35 after subtracting 102 from 137.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 51

Advancing to step 4:
355 divided by 51 is 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 306 from 355, we get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 51

On to step 5:
The number 51 fits into 493 9 times, leaving a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 269.0
Subtract 459 from 493 to get 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 51

Let's proceed to step 6:
If we divide 344 by 51, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 2696.0
The remainder is 38 after subtracting 306 from 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
If we divide 380 by 51, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 2696.7
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.

Advancing to step 8:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2696.74
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2696.745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
50 divided by 51 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 2696.745
Deduct 0 from 50 and we're left 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.

Moving on to step 11:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 2696.74509
If we take 459 away from 500, we end up with 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 12:
When dividing 410 by 51, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2696.745098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
20 divided by 51 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2696.745098
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.

Going ahead to step 14:
If we divide 200 by 51, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 2696.74509803
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 2696.74509803 with a remainder of 4.7e-08.
