198417 divided by 18 
Let's see how many times 18 fits into 198417.

Let's proceed to step 1:
When dividing 1 by 18, we get 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.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 18

Advancing to step 2:
The number 18 fits into 19 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 18 from 19, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 18

On to step 3:
18 divided by 18 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 18 from 18, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 18

On to step 4:
The number 18 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 18

Step 5:
18 can be fit into 41 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 1102.0
Deduct 36 from 41 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 18

Advancing to step 6:
The number 18 fits into 57 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 11023.0
Subtract 54 from 57 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 18 fits into 30 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 11023.1
If we subtract 18 from 30, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
18 goes into 120 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 11023.16
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 18 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11023.166
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 11023.166 and a remainder of 0.0012.
