571005 ÷ 18 
The aim is to understand the frequency of 18 in 571005.

Advancing to step 1:
18 can be fit into 5 0 times, resulting in 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.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 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
Subtracting 54 from 57 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 18

Step 3:
18 goes into 31 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 18 from 31 and we're left with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 18

Step 4:
The number 18 fits into 130 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 317.0
The remainder is 4 after subtracting 126 from 130.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 18

Advancing to step 5:
When dividing 40 by 18, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3172.0
If we subtract 36 from 40, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 18

Step 6:
18 goes into 45 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 31722.0
Deduct 36 from 45 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31722.5
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31722.5
If we subtract 0 from 0, we get 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 9:
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: 31722.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 31722.5, and the remainder is 0.0.
