Let's divide 719770 by 18
The aim is to understand the frequency of 18 in 719770.

Advancing to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 18

Let's proceed to step 2:
The number 18 fits into 71 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 54 from 71 and we're left with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 18

On to step 3:
When dividing 179 by 18, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 162 from 179 leaves us with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 18

Step 4:
If we divide 177 by 18, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 399.0
Subtracting 162 from 177 leaves us with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 18

Let's proceed to step 5:
The number 18 fits into 157 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 3998.0
If we take 144 away from 157, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 18

Moving on to step 6:
18 can be fit into 130 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 39987.0
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 39987.2
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 18, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 39987.22
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 39987.22 with a balance of 0.004.
