We're dividing 122419 by 18 
The aim is to understand the frequency of 18 in 122419.

Let's proceed to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 18

Moving on to step 2:
The number 18 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 18

On to step 3:
The number 18 fits into 122 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 14 after subtracting 108 from 122.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 18

Step 4:
144 divided by 18 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 68.0
If we subtract 144 from 144, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 18

Step 5:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 680.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 18

On to step 6:
When dividing 19 by 18, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 6801.0
Deduct 18 from 19 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.

Advancing to step 7:
18 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6801.0
Subtracting 0 from 10 leaves us 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.

Step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 6801.05
Deduct 90 from 100 and we're left 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.

On to step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6801.055
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 6801.055 and a remainder of 0.001.
