308688 ÷ 19 
Let's see how many times 19 fits into 308688.

Moving on to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 19

On to step 2:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 19 from 30 to get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 19

Step 3:
118 divided by 19 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 114 from 118 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 19

Advancing to step 4:
19 can be fit into 46 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
The remainder is 8 after subtracting 38 from 46.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 19

Advancing to step 5:
When dividing 88 by 19, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1624.0
Subtract 76 from 88 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 19

Advancing to step 6:
128 divided by 19 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 16246.0
If we take 114 away from 128, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
19 goes into 140 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 16246.7
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 16246.73
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
If we divide 130 by 19, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16246.736
The remainder is 16 after subtracting 114 from 130.
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 10:
19 goes into 160 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 16246.7368
Subtracting 152 from 160 leaves us 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.

Moving on to step 11:
80 divided by 19 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 16246.73684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 19, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 16246.736842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 19, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 16246.7368421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 16246.7368421
If we take 0 away from 10, we end up 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.

The final outcome is 16246.7368421, with a leftover of 1e-08.
