11835 ÷ 18 
The aim is to understand the frequency of 18 in 11835.

Let's proceed to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 18

Advancing to step 2:
18 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 18

Let's proceed to step 3:
18 can be fit into 118 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 10 after subtracting 108 from 118.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 18

Moving on to step 4:
If we divide 103 by 18, we get 5 and a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 13 after subtracting 90 from 103.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 18

Advancing to step 5:
If we divide 135 by 18, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 657.0
If we subtract 126 from 135, 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.

On to step 6:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 657.5
If we take 90 away from 90, we end up 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.

Advancing to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 657.5
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.

On to step 8:
18 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 657.5
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.

The final outcome is 657.5, with a leftover of 0.0.
