We divide 890888 by 18
The aim is to understand the frequency of 18 in 890888.

Let's proceed to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 18

Going ahead to step 2:
The number 18 fits into 89 4 times, leaving a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 72 away from 89, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 18

Moving on to step 3:
If we divide 170 by 18, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 162 from 170 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 18

Advancing to step 4:
18 can be fit into 88 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
Subtract 72 from 88 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 18

Advancing to step 5:
If we divide 168 by 18, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 4949.0
If we take 162 away from 168, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 18

Let's proceed to step 6:
When dividing 68 by 18, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 49493.0
If we take 54 away from 68, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 18, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 49493.7
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 49493.77
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 49493.77 with a remaining 0.014.
