578194 ÷ 18 
We're looking to find how many times 18 goes into 578194.

Going ahead to step 1:
18 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 18

Advancing to step 2:
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: 3.0
Subtracting 54 from 57 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 18

Advancing to step 3:
38 divided by 18 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 2 after subtracting 36 from 38.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 18

Going ahead to step 4:
21 divided by 18 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtracting 18 from 21 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 18

On to step 5:
If we divide 39 by 18, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 3212.0
Subtract 36 from 39 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 18

Step 6:
The number 18 fits into 34 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 32121.0
Subtracting 18 from 34 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
18 goes into 160 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 32121.8
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
160 divided by 18 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 32121.88
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 32121.88 and a remainder of 0.016.
