We divide 825840 by 54
The aim is to understand the frequency of 54 in 825840.

Step 1:
54 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 54

Let's proceed to step 2:
When dividing 82 by 54, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 54 from 82, we get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 54

Let's proceed to step 3:
54 can be fit into 285 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 270 from 285, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 54

Going ahead to step 4:
If we divide 158 by 54, we get 2 and a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we subtract 108 from 158, we get 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 54

Going ahead to step 5:
504 divided by 54 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 1529.0
Subtract 486 from 504 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 54

On to step 6:
The number 54 fits into 180 3 times, leaving a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 15293.0
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 54, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 15293.3
Subtract 162 from 180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 54, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 15293.33
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 15293.33 with a remaining 0.018.
