We're dividing 300869 by 18 
The aim is to understand the frequency of 18 in 300869.

Let's proceed to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 18

Let's proceed to step 2:
When dividing 30 by 18, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 18 from 30, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 18

Step 3:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 12 after subtracting 108 from 120.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 18

Going ahead to step 4:
18 goes into 128 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 167.0
The remainder is 2 after subtracting 126 from 128.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 18

Advancing to step 5:
The number 18 fits into 26 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1671.0
If we take 18 away from 26, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 18

Going ahead to step 6:
When dividing 89 by 18, we get 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 16714.0
If we take 72 away from 89, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
If we divide 170 by 18, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 16714.9
Subtracting 162 from 170 leaves us 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.

Moving on to step 8:
If we divide 80 by 18, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 16714.94
Deduct 72 from 80 and we're left 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.

Moving on to step 9:
If we divide 80 by 18, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16714.944
Deduct 72 from 80 and we're left 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.

Our division results in 16714.944 with a remaining 0.0008.
