We're dividing 347351 by 51 
The aim is to understand the frequency of 51 in 347351.

Step 1:
51 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 51

Going ahead to step 2:
51 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 51

Let's proceed to step 3:
51 can be fit into 347 6 times, resulting in a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 306 from 347 to get 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 51

Moving on to step 4:
If we divide 413 by 51, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 408 from 413 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 51

Moving on to step 5:
If we divide 55 by 51, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 681.0
Subtract 51 from 55 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 51

Advancing to step 6:
If we divide 41 by 51, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 6810.0
If we subtract 0 from 41, we 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.

Step 7:
When dividing 410 by 51, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 6810.8
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 8:
51 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6810.8
Deduct 0 from 20 and we're left with 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 9:
51 goes into 200 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 6810.803
Subtract 153 from 200 to 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 10:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 6810.8039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
51 goes into 110 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 6810.80392
If we take 102 away from 110, we end up 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.

On to step 12:
If we divide 80 by 51, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 6810.803921
If we subtract 51 from 80, we 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.

Moving on to step 13:
If we divide 290 by 51, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6810.8039215
Subtracting 255 from 290 leaves us 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 14:
51 can be fit into 350 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6810.80392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 6810.80392156 with a remainder of 4.4e-08.
