We divide 330570 by 18
The aim is to understand the frequency of 18 in 330570.

Going ahead to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

Advancing to step 2:
18 goes into 33 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 18 from 33 to get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 18

Let's proceed to step 3:
18 goes into 150 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 144 from 150 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 18

On to step 4:
The number 18 fits into 65 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we take 54 away from 65, we end up with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 18

On to step 5:
When dividing 117 by 18, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 1836.0
Subtracting 108 from 117 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 18

Step 6:
When dividing 90 by 18, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18365.0
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18365.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 18 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18365.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 18365.0, and the remainder is 0.0.
