Let's divide 289315 by 18
The aim is to understand the frequency of 18 in 289315.

Step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 18

Advancing to step 2:
The number 18 fits into 28 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 18 from 28, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 18

Step 3:
109 divided by 18 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 108 away from 109, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 18

Let's proceed to step 4:
18 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we subtract 0 from 13, we get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 18

Advancing to step 5:
If we divide 131 by 18, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1607.0
Deduct 126 from 131 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 18

Step 6:
If we divide 55 by 18, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 16073.0
Deduct 54 from 55 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.

Let's proceed to step 7:
If we divide 10 by 18, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 16073.0
If we take 0 away from 10, we end up 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.

Let's proceed to step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 16073.05
If we take 90 away from 100, we end up 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.

Let's proceed to step 9:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 16073.055
If we take 90 away from 100, we end up 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.

Our division results in 16073.055 with a remaining 0.001.
