We look at the division of 323575 by 51 
The aim is to understand the frequency of 51 in 323575.

Advancing to step 1:
The number 51 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 51

On to step 2:
32 divided by 51 is 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 51

Going ahead to step 3:
When dividing 323 by 51, we get 6 with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 306 from 323 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 51

Going ahead to step 4:
If we divide 175 by 51, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 153 from 175 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 51

Step 5:
51 can be fit into 227 4 times, resulting in a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 634.0
If we subtract 204 from 227, we get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 51

Let's proceed to step 6:
51 can be fit into 235 4 times, resulting in a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 6344.0
The remainder is 31 after subtracting 204 from 235.
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 7:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6344.6
Deduct 306 from 310 and we're left 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.

On to step 8:
If we divide 40 by 51, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6344.6
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.

Let's proceed to step 9:
If we divide 400 by 51, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 6344.607
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
430 divided by 51 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 6344.6078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 51, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 6344.60784
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
When dividing 160 by 51, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 6344.607843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
When dividing 70 by 51, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 6344.6078431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 6344.60784313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 6344.60784313 with a balance of 3.7e-08.
