Let's divide 512510 by 54
The aim is to understand the frequency of 54 in 512510.

Advancing to step 1:
54 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 54

Moving on to step 2:
If we divide 51 by 54, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 54

Let's proceed to step 3:
When dividing 512 by 54, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 26 after subtracting 486 from 512.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 54

Step 4:
The number 54 fits into 265 4 times, leaving a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 216 from 265 and we're left with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 54

On to step 5:
When dividing 491 by 54, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 949.0
Subtracting 486 from 491 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 54

Moving on to step 6:
If we divide 50 by 54, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 9490.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 54, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 9490.9
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 54 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 9490.92
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 54 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 9490.925
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 9490.9259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 54 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 9490.92592
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
The number 54 fits into 320 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9490.925925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
54 goes into 500 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 9490.9259259
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 9490.92592592
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 9490.92592592, and the remainder is 3.2e-08.
