We divide 802183 by 18
The aim is to understand the frequency of 18 in 802183.

Let's proceed to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 18

Moving on to step 2:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 72 from 80 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 18

Going ahead to step 3:
18 goes into 82 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 72 from 82 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 18

Advancing to step 4:
101 divided by 18 is 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 445.0
Deduct 90 from 101 and we're left with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 18

Going ahead to step 5:
118 divided by 18 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 4456.0
Deduct 108 from 118 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 18

Advancing to step 6:
If we divide 103 by 18, we get 5 and a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 44565.0
Subtract 90 from 103 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 44565.7
Subtract 126 from 130 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:
40 divided by 18 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 44565.72
Subtracting 36 from 40 leaves us 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.

Let's proceed to step 9:
When dividing 40 by 18, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 44565.722
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.

The quotient of the division is 44565.722, and the remainder is 0.0004.
