We look at the division of 803692 by 18 
The aim is to understand the frequency of 18 in 803692.

Let's proceed to step 1:
18 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 18

Advancing to step 2:
18 goes into 80 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 72 away from 80, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 18

On to step 3:
The number 18 fits into 83 4 times, leaving a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 72 from 83 and we're left with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 18

On to step 4:
When dividing 116 by 18, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 446.0
Subtract 108 from 116 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

Let's proceed to step 5:
The number 18 fits into 89 4 times, leaving a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4464.0
Deduct 72 from 89 and we're left with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 18

Let's proceed to step 6:
The number 18 fits into 172 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 44649.0
If we subtract 162 from 172, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 44649.5
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 44649.55
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 44649.55, and the remainder is 0.01.
