293236 divided by 18 
The aim is to understand the frequency of 18 in 293236.

Going ahead to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 18

Step 2:
18 goes into 29 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 18 from 29, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 18

On to step 3:
The number 18 fits into 113 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 108 from 113, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 18

Going ahead to step 4:
The number 18 fits into 52 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 162.0
Subtract 36 from 52 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 18

On to step 5:
18 goes into 163 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1629.0
Subtracting 162 from 163 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 18

Advancing to step 6:
18 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 16290.0
The remainder is 16 after subtracting 0 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 16290.8
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 16290.88
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 16290.88, with a leftover of 0.016.
