942485 ÷ 18 
The aim is to understand the frequency of 18 in 942485.

Let's proceed to step 1:
18 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 18

Let's proceed to step 2:
The number 18 fits into 94 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 90 from 94 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 18

Let's proceed to step 3:
42 divided by 18 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 36 away from 42, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Step 4:
When dividing 64 by 18, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 523.0
If we take 54 away from 64, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 18

Step 5:
If we divide 108 by 18, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 5236.0
If we subtract 108 from 108, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 18

Going ahead to step 6:
If we divide 5 by 18, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 52360.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 18, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 52360.2
If we take 36 away from 50, 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.

On to step 8:
140 divided by 18 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 52360.27
If we subtract 126 from 140, we 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.

Advancing to step 9:
140 divided by 18 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 52360.277
If we subtract 126 from 140, we 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.

The final result is 52360.277 with a remainder of 0.0014.
