We're dividing 80441 by 18 
The aim is to understand the frequency of 18 in 80441.

Moving on to step 1:
18 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 18

Let's proceed to step 2:
When dividing 80 by 18, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 80, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 18

Let's proceed to step 3:
18 can be fit into 84 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we take 72 away from 84, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 18

Step 4:
If we divide 124 by 18, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 446.0
Subtract 108 from 124 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 18

Going ahead to step 5:
18 goes into 161 8 times with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 4468.0
Subtracting 144 from 161 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 6:
The number 18 fits into 170 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4468.9
If we subtract 162 from 170, we 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.

On to step 7:
If we divide 80 by 18, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4468.94
The remainder is 8 after subtracting 72 from 80.
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:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4468.944
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 4468.944 and a remainder of 0.0008.
