We look at the division of 329091 by 51 
The aim is to understand the frequency of 51 in 329091.

Moving on 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
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 51

Step 2:
If we divide 32 by 51, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 51

Advancing to step 3:
The number 51 fits into 329 6 times, leaving a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 306 from 329 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 51

On to step 4:
When dividing 230 by 51, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 204 away from 230, we end up with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 51

Going ahead to step 5:
When dividing 269 by 51, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 645.0
Deduct 255 from 269 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 51

Let's proceed to step 6:
51 can be fit into 141 2 times, resulting in a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 6452.0
Subtract 102 from 141 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
When dividing 390 by 51, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 6452.7
The remainder is 33 after subtracting 357 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
When dividing 330 by 51, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 6452.76
Subtracting 306 from 330 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
51 goes into 240 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 6452.764
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 51, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 6452.7647
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6452.7647
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
51 goes into 300 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 6452.764705
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
51 can be fit into 450 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 6452.7647058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
51 can be fit into 420 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 6452.76470588
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 6452.76470588 with a balance of 1.2e-08.
