We're dividing 515950 by 54 
The aim is to understand the frequency of 54 in 515950.

On to step 1:
If we divide 5 by 54, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 54

Let's proceed to step 2:
51 divided by 54 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 54

Moving on to step 3:
If we divide 515 by 54, we get 9 and a remainder of 29.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 486 from 515 and we're left with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 54

On to step 4:
When dividing 299 by 54, we get 5 with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
The remainder is 29 after subtracting 270 from 299.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 54

On to step 5:
295 divided by 54 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 955.0
The remainder is 25 after subtracting 270 from 295.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 54

Step 6:
If we divide 250 by 54, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 9554.0
Deduct 216 from 250 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
54 can be fit into 340 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9554.6
Subtracting 324 from 340 leaves us 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.

On to step 8:
If we divide 160 by 54, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 9554.62
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
520 divided by 54 is 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 9554.629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
54 goes into 340 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 9554.6296
Subtracting 324 from 340 leaves us 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.

Moving on to step 11:
160 divided by 54 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 9554.62962
The remainder is 52 after subtracting 108 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
520 divided by 54 is 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 9554.629629
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
54 can be fit into 340 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 9554.6296296
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 54 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 9554.62962962
Subtracting 108 from 160 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 9554.62962962 with a balance of 5.2e-08.
