We divide 439389 by 54
The aim is to understand the frequency of 54 in 439389.

Step 1:
The number 54 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 54

Moving on to step 2:
If we divide 43 by 54, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 54

Step 3:
54 goes into 439 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 432 away from 439, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 54

Let's proceed to step 4:
73 divided by 54 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 54 from 73, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 54

Step 5:
198 divided by 54 is 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 813.0
Deduct 162 from 198 and we're left with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 54

Advancing to step 6:
The number 54 fits into 369 6 times, leaving a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 8136.0
The remainder is 45 after subtracting 324 from 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
450 divided by 54 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 8136.8
Subtracting 432 from 450 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.

Let's proceed to step 8:
54 goes into 180 3 times with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 8136.83
The remainder is 18 after subtracting 162 from 180.
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 9:
54 goes into 180 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 8136.833
Deduct 162 from 180 and we're left 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.

In conclusion, the division gives 8136.833 with a balance of 0.0018.
