265879 divided by 18 
The aim is to understand the frequency of 18 in 265879.

Moving on to step 1:
2 divided by 18 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 18

Advancing to step 2:
18 goes into 26 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 18 from 26, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 18

Advancing to step 3:
The number 18 fits into 85 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 72 from 85, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 18

Moving on to step 4:
18 can be fit into 138 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 147.0
Subtract 126 from 138 to get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 18

Let's proceed to step 5:
127 divided by 18 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1477.0
If we subtract 126 from 127, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 18

Advancing to step 6:
19 divided by 18 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 14771.0
Deduct 18 from 19 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
18 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14771.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 14771.05
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 18, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 14771.055
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 14771.055 with a remainder of 0.001.
