389049 ÷ 54 
The aim is to understand the frequency of 54 in 389049.

Step 1:
The number 54 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 54

Step 2:
38 divided by 54 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 54

Step 3:
When dividing 389 by 54, we get 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 378 from 389 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 54

Let's proceed to step 4:
When dividing 110 by 54, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 108 from 110 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 54

Going ahead to step 5:
54 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
Subtracting 0 from 24 leaves us with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 54

Moving on to step 6:
When dividing 249 by 54, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 7204.0
If we subtract 216 from 249, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
54 goes into 330 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 7204.6
Subtract 324 from 330 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 54, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 7204.61
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
54 goes into 60 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 7204.611
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 7204.611 with a remaining 0.0006.
