We look at the division of 911458 by 18 
The aim is to understand the frequency of 18 in 911458.

Advancing to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 18

Advancing to step 2:
18 can be fit into 91 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 90 from 91 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 18

Moving on to step 3:
18 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 11, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 18

Step 4:
18 can be fit into 114 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 506.0
Deduct 108 from 114 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 18

Step 5:
If we divide 65 by 18, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 5063.0
Subtract 54 from 65 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 18

Moving on to step 6:
18 goes into 118 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 50636.0
Deduct 108 from 118 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
18 goes into 100 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 50636.5
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 50636.55
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 50636.55 and a remainder of 0.01.
