824888 ÷ 18 
The aim is to understand the frequency of 18 in 824888.

Going ahead 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
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 18

Advancing to step 2:
When dividing 82 by 18, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 72 from 82 leaves us with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 18

On to step 3:
When dividing 104 by 18, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 90 from 104 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 18

On to step 4:
148 divided by 18 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
Deduct 144 from 148 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 18

Moving on to step 5:
The number 18 fits into 48 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 4582.0
If we subtract 36 from 48, we get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 18

Let's proceed to step 6:
If we divide 128 by 18, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 45827.0
Deduct 126 from 128 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
18 goes into 20 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 45827.1
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
18 goes into 20 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 45827.11
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 45827.11 with a remaining 0.002.
