417358 ÷ 18 
The aim is to understand the frequency of 18 in 417358.

Step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 18

Moving on to step 2:
18 goes into 41 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 36 from 41 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 18

Step 3:
18 can be fit into 57 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 54 from 57 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 18

Let's proceed to step 4:
18 goes into 33 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
If we take 18 away from 33, we end up with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 18

Step 5:
If we divide 155 by 18, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 2318.0
If we take 144 away from 155, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 18

On to step 6:
18 can be fit into 118 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 23186.0
Subtracting 108 from 118 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
18 goes into 100 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 23186.5
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 23186.55
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 23186.55, and the remainder is 0.01.
