261492 ÷ 18 
The aim is to understand the frequency of 18 in 261492.

Let's proceed to step 1:
If we divide 2 by 18, we get 0 and 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.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 18

Going ahead to step 2:
When dividing 26 by 18, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 18 from 26 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 18

Advancing to step 3:
18 can be fit into 81 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 72 from 81 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 18

Moving on to step 4:
The number 18 fits into 94 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Subtracting 90 from 94 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 18

Step 5:
When dividing 49 by 18, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 1452.0
If we subtract 36 from 49, we get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 18

Moving on to step 6:
132 divided by 18 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 14527.0
Deduct 126 from 132 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 14527.3
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 14527.33
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 14527.33 with a balance of 0.006.
