Let's divide 827968 by 18
The aim is to understand the frequency of 18 in 827968.

On to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 18

Let's proceed to step 2:
If we divide 82 by 18, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 10 after subtracting 72 from 82.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 18

On to step 3:
18 can be fit into 107 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 90 from 107 and we're left with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 18

On to step 4:
18 goes into 179 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Deduct 162 from 179 and we're left with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 18

Step 5:
18 can be fit into 176 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 4599.0
Subtracting 162 from 176 leaves us with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 18

On to step 6:
18 can be fit into 148 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 45998.0
Subtract 144 from 148 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.

Step 7:
40 divided by 18 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 45998.2
Subtract 36 from 40 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:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 45998.22
Deduct 36 from 40 and we're left 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.

In conclusion, the division gives 45998.22 with a balance of 0.004.
