We look at the division of 393041 by 51 
The aim is to understand the frequency of 51 in 393041.

Advancing to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 51

Advancing to step 2:
The number 51 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 51

Moving on to step 3:
If we divide 393 by 51, we get 7 and a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 36 after subtracting 357 from 393.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 51

Advancing to step 4:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 357 from 360, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 51

Step 5:
34 divided by 51 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 770.0
Subtract 0 from 34 to get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 51

Advancing to step 6:
51 goes into 341 6 times with a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 7706.0
The remainder is 35 after subtracting 306 from 341.
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 7:
350 divided by 51 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 7706.6
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.

Step 8:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 7706.68
Subtracting 408 from 440 leaves us with 32.
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 9:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 7706.686
Subtracting 306 from 320 leaves us with 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 10:
The number 51 fits into 140 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 7706.6862
If we take 102 away from 140, we end up with 38.
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 11:
51 can be fit into 380 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 7706.68627
If we take 357 away from 380, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
The number 51 fits into 230 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 7706.686274
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.

On to step 13:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7706.6862745
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
When dividing 50 by 51, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7706.6862745
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.

The final result is 7706.6862745 with a remainder of 5e-08.
