902670 divided by 18 
The aim is to understand the frequency of 18 in 902670.

On to step 1:
The number 18 fits into 9 0 times, leaving 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.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 18

Advancing to step 2:
18 goes into 90 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 90 from 90 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 18

Let's proceed to step 3:
18 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 18

On to step 4:
The number 18 fits into 26 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 501.0
Deduct 18 from 26 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 18

Step 5:
If we divide 87 by 18, we get 4 and a remainder of 15.
The next digit of our result is 4. 
Result so far: 5014.0
Subtract 72 from 87 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 18

Step 6:
The number 18 fits into 150 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 50148.0
Subtracting 144 from 150 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.

Going ahead to step 7:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 50148.3
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.

On to step 8:
60 divided by 18 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 50148.33
Deduct 54 from 60 and we're left 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.

In conclusion, the division gives 50148.33 with a balance of 0.006.
