We're dividing 306209 by 19 
We want to divide 306209 by 19.

Going ahead to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 19

Going ahead to step 2:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 19 from 30 leaves us with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 19

Moving on to step 3:
If we divide 116 by 19, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 2 after subtracting 114 from 116.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 19

Going ahead to step 4:
When dividing 22 by 19, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Subtract 19 from 22 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 19

Moving on to step 5:
If we divide 30 by 19, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1611.0
Subtracting 19 from 30 leaves us with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 19

Step 6:
The number 19 fits into 119 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 16116.0
Deduct 114 from 119 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 19, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 16116.2
Deduct 38 from 50 and we're left with 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 8:
120 divided by 19 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 16116.26
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
19 goes into 60 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 16116.263
Subtract 57 from 60 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 10:
30 divided by 19 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 16116.2631
Deduct 19 from 30 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 16116.26315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
If we divide 150 by 19, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 16116.263157
Subtract 133 from 150 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.

Going ahead to step 13:
When dividing 170 by 19, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 16116.2631578
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 19 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 16116.26315789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 16116.26315789, with a leftover of 9e-09.
