We're dividing 189632 by 18 
The aim is to understand the frequency of 18 in 189632.

Step 1:
18 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 18

Let's proceed to step 2:
The number 18 fits into 18 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 18 away from 18, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 18

Step 3:
If we divide 9 by 18, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 18

Moving on to step 4:
18 goes into 96 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 90 away from 96, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 18

Step 5:
63 divided by 18 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 1053.0
Subtract 54 from 63 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 18

Step 6:
92 divided by 18 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 10535.0
Subtract 90 from 92 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 18, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 10535.1
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 18 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 10535.11
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 10535.11, and the remainder is 0.002.
