We're dividing 898969 by 18 
The aim is to understand the frequency of 18 in 898969.

Moving on to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 18

Let's proceed to step 2:
If we divide 89 by 18, we get 4 and a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 17 after subtracting 72 from 89.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 18

Advancing to step 3:
The number 18 fits into 178 9 times, leaving a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 16 after subtracting 162 from 178.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 18

Let's proceed to step 4:
When dividing 169 by 18, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 499.0
The remainder is 7 after subtracting 162 from 169.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 18

Let's proceed to step 5:
The number 18 fits into 76 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4994.0
The remainder is 4 after subtracting 72 from 76.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 18

On to step 6:
18 can be fit into 49 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 49942.0
If we subtract 36 from 49, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
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: 49942.7
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 18, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 49942.72
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
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: 49942.722
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 49942.722, and the remainder is 0.0004.
