Let's divide 843044 by 18
The aim is to understand the frequency of 18 in 843044.

Let's proceed to step 1:
8 divided by 18 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 18

Advancing to step 2:
84 divided by 18 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 72 from 84, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 18

Going ahead to step 3:
18 can be fit into 123 6 times, resulting in a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 108 from 123 leaves us with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 18

Let's proceed to step 4:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 468.0
If we take 144 away from 150, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 18

Let's proceed to step 5:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 4683.0
Deduct 54 from 64 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 18

Moving on to step 6:
104 divided by 18 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 46835.0
Subtract 90 from 104 to 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.

Step 7:
If we divide 140 by 18, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 46835.7
If we take 126 away from 140, 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.

Going ahead to step 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 46835.77
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 quotient of the division is 46835.77, and the remainder is 0.014.
