489615 divided by 54 
The aim is to understand the frequency of 54 in 489615.

On to step 1:
The number 54 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 54

Advancing to step 2:
54 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 54

Advancing to step 3:
54 can be fit into 489 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 486 from 489 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 54

Let's proceed to step 4:
If we divide 36 by 54, we get 0 and a remainder of 36.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 36 leaves us with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 54

Advancing to step 5:
The number 54 fits into 361 6 times, leaving a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 906.0
Subtract 324 from 361 to get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 54

Step 6:
When dividing 375 by 54, we get 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 9066.0
If we subtract 324 from 375, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
54 goes into 510 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 9066.9
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
54 can be fit into 240 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 9066.94
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
54 can be fit into 240 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 9066.944
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 9066.944 with a remaining 0.0024.
