We're dividing 198359 by 18 
We want to figure out the number of times 198359 can be divided by 18.

Let's proceed to step 1:
1 divided by 18 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 18

Let's proceed to step 2:
When dividing 19 by 18, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 18 from 19 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 18

Going ahead to step 3:
The number 18 fits into 18 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
If we take 18 away from 18, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 18

Let's proceed to step 4:
18 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 18

Going ahead to step 5:
The number 18 fits into 35 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101.0
Subtracting 18 from 35 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 18

Going ahead to step 6:
If we divide 179 by 18, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 11019.0
Subtract 162 from 179 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 18, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 11019.9
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 11019.94
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 18, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 11019.944
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 11019.944, with a leftover of 0.0008.
