We're dividing 320413 by 54 
The aim is to understand the frequency of 54 in 320413.

Advancing to step 1:
If we divide 3 by 54, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 54

Moving on to step 2:
54 can be fit into 32 0 times, resulting in a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 54

Step 3:
54 goes into 320 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 270 from 320 to get 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 54

Let's proceed to step 4:
54 goes into 504 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 18 after subtracting 486 from 504.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 54

Step 5:
If we divide 181 by 54, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
If we take 162 away from 181, we end up with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 54

Moving on to step 6:
If we divide 193 by 54, we get 3 and a remainder of 31.
The next digit of our result is 3. 
Result so far: 5933.0
If we take 162 away from 193, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 54 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5933.5
Subtract 270 from 310 to 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.

Moving on to step 8:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 5933.57
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 54, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 5933.574
Deduct 216 from 220 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.

Advancing to step 10:
The number 54 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5933.574
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 54 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 5933.57407
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 5933.574074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 54 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5933.574074
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
If we divide 400 by 54, we get 7 and a remainder of 22.
The next digit of our result is 7. 
Result so far: 5933.57407407
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 5933.57407407 with a remainder of 2.2e-08.
