We divide 662445 by 18
The aim is to understand the frequency of 18 in 662445.

On to step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 18

Let's proceed to step 2:
18 goes into 66 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 12 after subtracting 54 from 66.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 18

Going ahead to step 3:
The number 18 fits into 122 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Deduct 108 from 122 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 18

On to step 4:
144 divided by 18 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 368.0
Subtract 144 from 144 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 18

Moving on to step 5:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 3680.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 18

Going ahead to step 6:
If we divide 45 by 18, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 36802.0
If we subtract 36 from 45, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 18, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 36802.5
If we subtract 90 from 90, we 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.

Moving on to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 36802.5
Subtracting 0 from 0 leaves us 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.

Step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36802.5
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.

Our division results in 36802.5 with a remaining 0.0.
