Let's divide 617460 by 18
The aim is to understand the frequency of 18 in 617460.

Step 1:
6 divided by 18 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 18

Advancing to step 2:
18 can be fit into 61 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 54 from 61 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 18

Moving on to step 3:
18 can be fit into 77 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 72 away from 77, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 18

Let's proceed to step 4:
The number 18 fits into 54 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 343.0
If we take 54 away from 54, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 18

Step 5:
6 divided by 18 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 3430.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 18

Advancing to step 6:
18 goes into 60 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 34303.0
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 18, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 34303.3
Subtracting 54 from 60 leaves us 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.

Step 8:
18 goes into 60 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 34303.33
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 34303.33, with a leftover of 0.006.
