We divide 229607 by 18
The aim is to understand the frequency of 18 in 229607.

On 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
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 18

Moving on to step 2:
22 divided by 18 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 18 from 22, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 18

Advancing to step 3:
The number 18 fits into 49 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 36 from 49 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 18

Advancing to step 4:
136 divided by 18 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we take 126 away from 136, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 18

On to step 5:
The number 18 fits into 100 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 1275.0
If we subtract 90 from 100, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 18

Advancing to step 6:
18 goes into 107 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 12755.0
The remainder is 17 after subtracting 90 from 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
18 goes into 170 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 12755.9
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 12755.94
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 18, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 12755.944
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 12755.944 with a remainder of 0.0008.
