We're dividing 682364 by 18 
The aim is to understand the frequency of 18 in 682364.

Advancing to step 1:
When dividing 6 by 18, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 18

Advancing to step 2:
18 can be fit into 68 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
If we take 54 away from 68, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 18

Let's proceed to step 3:
If we divide 142 by 18, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 126 away from 142, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 18

Let's proceed to step 4:
18 goes into 163 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 379.0
Deduct 162 from 163 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 18

Advancing to step 5:
18 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 3790.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 18

On to step 6:
If we divide 164 by 18, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 37909.0
If we subtract 162 from 164, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 18, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 37909.1
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 18 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 37909.11
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 37909.11 and a remainder of 0.002.
