We look at the division of 351341 by 51 
The aim is to understand the frequency of 51 in 351341.

Let's proceed to step 1:
The number 51 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 51

On to step 2:
If we divide 35 by 51, we get 0 and a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 51

Let's proceed to step 3:
351 divided by 51 is 6 with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 306 from 351 to get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 51

Going ahead to step 4:
51 can be fit into 453 8 times, resulting in a remainder of 45.
The next digit of our result is 8. 
Result so far: 68.0
If we take 408 away from 453, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 51

Going ahead to step 5:
454 divided by 51 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 688.0
If we subtract 408 from 454, we get 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 51

On to step 6:
The number 51 fits into 461 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 6889.0
If we take 459 away from 461, 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.

On to step 7:
If we divide 20 by 51, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 6889.0
Subtracting 0 from 20 leaves us 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.

Step 8:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 6889.03
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
51 goes into 470 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 6889.039
If we take 459 away from 470, we end up 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.

Step 10:
51 goes into 110 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6889.0392
If we subtract 102 from 110, we get 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 11:
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: 6889.03921
The remainder is 29 after subtracting 51 from 80.
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 12:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6889.039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
When dividing 350 by 51, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6889.0392156
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.

Moving on to step 14:
If we divide 440 by 51, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 6889.03921568
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.

After the division, we end up with 6889.03921568 and a remainder of 3.2e-08.
