702386 divided by 18 
The aim is to understand the frequency of 18 in 702386.

Let's proceed to step 1:
The number 18 fits into 7 0 times, leaving 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.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 18

Advancing to step 2:
When dividing 70 by 18, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
If we take 54 away from 70, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 18

Moving on to step 3:
When dividing 162 by 18, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 162 from 162 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 18

Moving on to step 4:
3 divided by 18 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 390.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 18

Let's proceed to step 5:
18 goes into 38 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 3902.0
Subtracting 36 from 38 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 18

Going ahead to step 6:
18 goes into 26 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 39021.0
If we take 18 away from 26, we end up 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.

On to step 7:
80 divided by 18 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 39021.4
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 18 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 39021.44
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.

The final outcome is 39021.44, with a leftover of 0.008.
