We're dividing 389076 by 18 
The aim is to understand the frequency of 18 in 389076.

Moving on to step 1:
18 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 18

Moving on to step 2:
38 divided by 18 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 36 away from 38, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 18

Let's proceed to step 3:
The number 18 fits into 29 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 18 from 29 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 18

Advancing to step 4:
If we divide 110 by 18, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Subtract 108 from 110 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 18

Let's proceed to step 5:
The number 18 fits into 27 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 2161.0
Subtract 18 from 27 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 18

Advancing to step 6:
When dividing 96 by 18, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 21615.0
If we take 90 away from 96, we end up 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.

Going ahead to step 7:
When dividing 60 by 18, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 21615.3
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.

Step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 21615.33
Deduct 54 from 60 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.

Our division results in 21615.33 with a remaining 0.006.
