135127 divided by 51 
The aim is to understand the frequency of 51 in 135127.

Step 1:
1 divided by 51 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 51

On to step 2:
51 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 51

Advancing to step 3:
135 divided by 51 is 2 with a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 33 after subtracting 102 from 135.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 51

On to step 4:
When dividing 331 by 51, we get 6 with a remainder of 25.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 306 from 331 to get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 51

Let's proceed to step 5:
252 divided by 51 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
If we subtract 204 from 252, we get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 51

Let's proceed to step 6:
51 goes into 487 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 2649.0
Deduct 459 from 487 and we're left with 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 7:
When dividing 280 by 51, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2649.5
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
51 can be fit into 250 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 2649.54
If we take 204 away from 250, we end up 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 9:
51 goes into 460 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2649.549
Subtract 459 from 460 to 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.

Let's proceed to step 10:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2649.549
If we take 0 away from 10, we end up 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.

Let's proceed to step 11:
When dividing 100 by 51, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 2649.54901
The remainder is 49 after subtracting 51 from 100.
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 12:
490 divided by 51 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 2649.549019
If we take 459 away from 490, we end up 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.

Moving on to step 13:
51 goes into 310 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2649.5490196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2649.5490196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 2649.5490196 with a remainder of 4e-08.
