190909 ÷ 18 
We want to divide 190909 by 18.

Going ahead to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 18

Step 2:
If we divide 19 by 18, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 18 from 19.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 18

Going ahead to step 3:
10 divided by 18 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 18

Moving on to step 4:
When dividing 109 by 18, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 1 after subtracting 108 from 109.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 18

Advancing to step 5:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1060.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 18

Advancing to step 6:
If we divide 109 by 18, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 10606.0
Subtracting 108 from 109 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 18 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10606.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10606.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
18 goes into 100 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10606.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 10606.055, with a leftover of 0.001.
