938474 ÷ 18 
The aim is to understand the frequency of 18 in 938474.

Let's proceed to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 18

Advancing to step 2:
When dividing 93 by 18, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 3 after subtracting 90 from 93.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 18

Let's proceed to step 3:
18 goes into 38 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 18

Moving on to step 4:
If we divide 24 by 18, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Subtracting 18 from 24 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 18

On to step 5:
If we divide 67 by 18, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 5213.0
The remainder is 13 after subtracting 54 from 67.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 18

Moving on to step 6:
The number 18 fits into 134 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 52137.0
The remainder is 8 after subtracting 126 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 18, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 52137.4
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 52137.44
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 52137.44 with a remaining 0.008.
