226726 divided by 18 
The aim is to understand the frequency of 18 in 226726.

Let's proceed to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 18

Let's proceed to step 2:
If we divide 22 by 18, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 18 from 22 to get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 18

Step 3:
18 can be fit into 46 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 36 from 46 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 18

On to step 4:
The number 18 fits into 107 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtract 90 from 107 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 18

Step 5:
The number 18 fits into 172 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 1259.0
If we subtract 162 from 172, we get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 18

Let's proceed to step 6:
The number 18 fits into 106 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 12595.0
If we take 90 away from 106, we end up 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.

Let's proceed to step 7:
If we divide 160 by 18, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 12595.8
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.

Going ahead to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12595.88
Deduct 144 from 160 and we're left 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.

In conclusion, the division gives 12595.88 with a balance of 0.016.
