Let's divide 13288239 by 18
The aim is to understand the frequency of 18 in 13288239.

Advancing to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 18

Step 2:
The number 18 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 18

Step 3:
18 goes into 132 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 6 after subtracting 126 from 132.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 18

Moving on to step 4:
If we divide 68 by 18, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 73.0
Subtracting 54 from 68 leaves us with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 18

Step 5:
18 goes into 148 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 738.0
The remainder is 4 after subtracting 144 from 148.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 18

Moving on to step 6:
18 goes into 42 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 7382.0
The remainder is 6 after subtracting 36 from 42.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 18

Moving on to step 7:
63 divided by 18 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 73823.0
If we take 54 away from 63, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 18

Going ahead to step 8:
The number 18 fits into 99 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 738235.0
If we subtract 90 from 99, 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 9:
90 divided by 18 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 738235.5
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.

Going ahead to step 10:
When dividing 0 by 18, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 738235.5
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.

Moving on to step 11:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 738235.5
Deduct 0 from 0 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.

The quotient of the division is 738235.5, and the remainder is 0.0.
