We look at the division of 180240 by 51 
The aim is to understand the frequency of 51 in 180240.

Step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 51

Going ahead to step 2:
When dividing 18 by 51, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 51

Moving on to step 3:
When dividing 180 by 51, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 27 after subtracting 153 from 180.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 51

Advancing to step 4:
If we divide 272 by 51, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 17 after subtracting 255 from 272.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 51

Let's proceed to step 5:
The number 51 fits into 174 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 353.0
If we take 153 away from 174, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 51

On to step 6:
51 can be fit into 210 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 3534.0
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
51 goes into 60 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 3534.1
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
90 divided by 51 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 3534.11
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 3534.11 with a balance of 0.039.
