Let's divide 585807 by 18
The aim is to understand the frequency of 18 in 585807.

Let's proceed to step 1:
If we divide 5 by 18, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 18

Step 2:
If we divide 58 by 18, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 54 from 58, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 18

On to step 3:
18 can be fit into 45 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 36 from 45 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 18

Let's proceed to step 4:
If we divide 98 by 18, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 325.0
Subtract 90 from 98 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 18

On to step 5:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 3254.0
Subtract 72 from 80 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 18

Going ahead to step 6:
18 goes into 87 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 32544.0
If we take 72 away from 87, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
150 divided by 18 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 32544.8
If we take 144 away from 150, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 32544.83
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
18 goes into 60 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 32544.833
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 32544.833 with a balance of 0.0006.
