We divide 687652 by 18
The aim is to understand the frequency of 18 in 687652.

On to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 18

Moving on to step 2:
If we divide 68 by 18, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 54 from 68 leaves us with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 18

Moving on to step 3:
18 can be fit into 147 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtract 144 from 147 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 18

Advancing to step 4:
18 can be fit into 36 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 382.0
If we take 36 away from 36, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 18

Let's proceed to step 5:
5 divided by 18 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 3820.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 18

Let's proceed to step 6:
18 goes into 52 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 38202.0
Subtract 36 from 52 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
If we divide 160 by 18, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 38202.8
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
18 goes into 160 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 38202.88
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 38202.88 with a balance of 0.016.
