985584 divided by 54 
The aim is to understand the frequency of 54 in 985584.

On to step 1:
54 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 54

Step 2:
The number 54 fits into 98 1 times, leaving a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 54 away from 98, we end up with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 54

Moving on to step 3:
445 divided by 54 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 18.0
If we take 432 away from 445, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 54

Let's proceed to step 4:
54 goes into 135 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 182.0
Deduct 108 from 135 and we're left with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 54

Step 5:
54 goes into 278 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 1825.0
The remainder is 8 after subtracting 270 from 278.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 54

On to step 6:
84 divided by 54 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 18251.0
Deduct 54 from 84 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
54 goes into 300 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 18251.5
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
54 can be fit into 300 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 18251.55
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 18251.55 with a remaining 0.03.
