We divide 801427 by 18
The aim is to understand the frequency of 18 in 801427.

Moving on to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 18

Moving on to step 2:
If we divide 80 by 18, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 72 away from 80, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 18

Moving on to step 3:
18 goes into 81 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 72 away from 81, we end up with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 18

Let's proceed to step 4:
18 can be fit into 94 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
The remainder is 4 after subtracting 90 from 94.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 18

Let's proceed to step 5:
If we divide 42 by 18, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 4452.0
If we subtract 36 from 42, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 18

Advancing to step 6:
The number 18 fits into 67 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 44523.0
Subtracting 54 from 67 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
18 goes into 130 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 44523.7
Subtract 126 from 130 to get 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 8:
18 goes into 40 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 44523.72
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.

Advancing to step 9:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 44523.722
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.

After the division, we end up with 44523.722 and a remainder of 0.0004.
