We divide 573722 by 18
The aim is to understand the frequency of 18 in 573722.

Advancing to step 1:
18 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 18

Advancing to step 2:
18 goes into 57 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 54 from 57.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 18

Moving on to step 3:
18 goes into 33 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 18 from 33 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 18

Step 4:
If we divide 157 by 18, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 318.0
The remainder is 13 after subtracting 144 from 157.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 18

Going ahead to step 5:
If we divide 132 by 18, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 3187.0
If we subtract 126 from 132, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 18

Let's proceed to step 6:
The number 18 fits into 62 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 31873.0
If we take 54 away from 62, 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.

Going ahead to step 7:
When dividing 80 by 18, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 31873.4
Subtracting 72 from 80 leaves us 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.

Moving on to step 8:
When dividing 80 by 18, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 31873.44
Subtract 72 from 80 to 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.

In conclusion, the division gives 31873.44 with a balance of 0.008.
