Let's divide 968442 by 18
The aim is to understand the frequency of 18 in 968442.

Advancing to step 1:
18 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 18

Moving on to step 2:
When dividing 96 by 18, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 90 from 96 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 18

Advancing to step 3:
The number 18 fits into 68 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 54 from 68 leaves us with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 18

Moving on to step 4:
The number 18 fits into 144 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 538.0
Subtract 144 from 144 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 18

Moving on to step 5:
If we divide 4 by 18, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 5380.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 18

On to step 6:
18 goes into 42 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 53802.0
Subtract 36 from 42 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 18 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 53802.3
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 18, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 53802.33
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 53802.33 with a remainder of 0.006.
