329741 ÷ 18 
The aim is to understand the frequency of 18 in 329741.

Let's proceed to step 1:
18 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 18

Moving on to step 2:
18 goes into 32 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 18 from 32, we get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 18

Step 3:
18 goes into 149 8 times with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 144 from 149 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 18

Advancing to step 4:
The number 18 fits into 57 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we subtract 54 from 57, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 18

Step 5:
If we divide 34 by 18, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1831.0
Subtracting 18 from 34 leaves us with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 18

Step 6:
18 goes into 161 8 times with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 18318.0
Deduct 144 from 161 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 18 fits into 170 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 18318.9
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
When dividing 80 by 18, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 18318.94
Subtracting 72 from 80 leaves us 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.

Going ahead to step 9:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 18318.944
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.

After the division, we end up with 18318.944 and a remainder of 0.0008.
