438945 divided by 18 
The aim is to understand the frequency of 18 in 438945.

Advancing to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 18

Going ahead to step 2:
When dividing 43 by 18, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 36 from 43 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 18

On to step 3:
18 goes into 78 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 72 away from 78, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 18

Moving on to step 4:
18 can be fit into 69 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 243.0
Subtract 54 from 69 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 18

Step 5:
If we divide 154 by 18, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 2438.0
The remainder is 10 after subtracting 144 from 154.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 18

Moving on to step 6:
18 goes into 105 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 24385.0
Subtract 90 from 105 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 24385.8
If we take 144 away from 150, 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.

Let's proceed to step 8:
When dividing 60 by 18, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 24385.83
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.

On to step 9:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 24385.833
Subtracting 54 from 60 leaves us 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.

In conclusion, the division gives 24385.833 with a balance of 0.0006.
