65224258 divided by 18 
The aim is to understand the frequency of 18 in 65224258.

On to step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 18

Moving on to step 2:
18 can be fit into 65 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 54 from 65 leaves us with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 18

Going ahead to step 3:
The number 18 fits into 112 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we subtract 108 from 112, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 18

Moving on to step 4:
If we divide 42 by 18, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 362.0
Deduct 36 from 42 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Step 5:
If we divide 64 by 18, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3623.0
If we subtract 54 from 64, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 18

Going ahead to step 6:
If we divide 102 by 18, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 36235.0
Subtracting 90 from 102 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 18

Step 7:
18 can be fit into 125 6 times, resulting in a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 362356.0
If we subtract 108 from 125, we get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 18

Advancing to step 8:
178 divided by 18 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 3623569.0
Subtracting 162 from 178 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3623569.8
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 18, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3623569.88
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 3623569.88 with a remainder of 0.016.
