We're dividing 719236 by 18 
The aim is to understand the frequency of 18 in 719236.

Step 1:
18 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Moving on to step 2:
When dividing 71 by 18, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 54 from 71 and we're left with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 18

Step 3:
18 can be fit into 179 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 162 away from 179, we end up with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 18

Moving on to step 4:
172 divided by 18 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 399.0
Subtract 162 from 172 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 18

Step 5:
103 divided by 18 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 3995.0
If we take 90 away from 103, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 18

Let's proceed to step 6:
18 goes into 136 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 39957.0
Subtracting 126 from 136 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.

Going ahead to step 7:
When dividing 100 by 18, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 39957.5
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.

Advancing to step 8:
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: 39957.55
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.

In conclusion, the division gives 39957.55 with a balance of 0.01.
