We're dividing 612507 by 54 
The aim is to understand the frequency of 54 in 612507.

Step 1:
54 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 54

Advancing to step 2:
If we divide 61 by 54, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 7 after subtracting 54 from 61.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 54

Moving on to step 3:
54 can be fit into 72 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 54 from 72 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 54

Let's proceed to step 4:
If we divide 185 by 54, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 113.0
Deduct 162 from 185 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 54

Going ahead to step 5:
If we divide 230 by 54, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1134.0
If we subtract 216 from 230, we get 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 54

Moving on to step 6:
54 goes into 147 2 times with a remainder of 39.
The next digit of our result is 2. 
Result so far: 11342.0
If we take 108 away from 147, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 54, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 11342.7
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
54 can be fit into 120 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 11342.72
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 54 fits into 120 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 11342.722
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 11342.722, and the remainder is 0.0012.
