We're dividing 457887 by 54 
The aim is to understand the frequency of 54 in 457887.

Advancing to step 1:
If we divide 4 by 54, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 54

Going ahead to step 2:
54 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 54

Going ahead to step 3:
When dividing 457 by 54, we get 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 432 from 457 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 54

On to step 4:
If we divide 258 by 54, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 216 from 258 to get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 54

Going ahead to step 5:
54 can be fit into 428 7 times, resulting in a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 847.0
Subtract 378 from 428 to get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 54

Step 6:
507 divided by 54 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 8479.0
The remainder is 21 after subtracting 486 from 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
54 goes into 210 3 times with a remainder of 48.
The next digit of our result is 3. 
Result so far: 8479.3
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
When dividing 480 by 54, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8479.38
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 54, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 8479.388
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 8479.388 and a remainder of 0.0048.
