Let's divide 583524 by 18
The aim is to understand the frequency of 18 in 583524.

Going ahead to step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 18

Step 2:
18 goes into 58 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 54 from 58 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 18

On to step 3:
18 can be fit into 43 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 36 away from 43, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 18

On to step 4:
18 can be fit into 75 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
If we subtract 72 from 75, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 18

Going ahead to step 5:
18 goes into 32 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 3241.0
Subtract 18 from 32 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 18

Let's proceed to step 6:
18 can be fit into 144 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 32418.0
Subtracting 144 from 144 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32418.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 18 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32418.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 32418.0 and a remainder of 0.0.
