Let's divide 671885 by 54
The aim is to understand the frequency of 54 in 671885.

Moving on to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 54

On to step 2:
67 divided by 54 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 54 from 67.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 54

Let's proceed to step 3:
If we divide 131 by 54, we get 2 and a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 108 from 131, we get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 54

Let's proceed to step 4:
If we divide 238 by 54, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 124.0
If we take 216 away from 238, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 54

Advancing to step 5:
When dividing 228 by 54, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 1244.0
Subtract 216 from 228 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 54

Step 6:
When dividing 125 by 54, we get 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 12442.0
Subtract 108 from 125 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
54 goes into 170 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 12442.3
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
54 can be fit into 80 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 12442.31
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 54 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 12442.314
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
When dividing 440 by 54, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 12442.3148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 54 fits into 80 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 12442.31481
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
If we divide 260 by 54, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 12442.314814
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
When dividing 440 by 54, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 12442.3148148
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
80 divided by 54 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 12442.31481481
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 12442.31481481, with a leftover of 2.6e-08.
