We look at the division of 308520 by 19 
We want to divide 308520 by 19.

Step 1:
When dividing 3 by 19, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 19

Going ahead to step 2:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 19 from 30 and we're left with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 19

Moving on to step 3:
19 goes into 118 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 114 from 118, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 19

Let's proceed to step 4:
19 can be fit into 45 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Subtract 38 from 45 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 19

Going ahead to step 5:
72 divided by 19 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 1623.0
The remainder is 15 after subtracting 57 from 72.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 19

Step 6:
If we divide 150 by 19, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 16237.0
If we subtract 133 from 150, we 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 7:
When dividing 170 by 19, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 16237.8
Subtracting 152 from 170 leaves us 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.

Step 8:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 16237.89
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.

Advancing to step 9:
The number 19 fits into 90 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 16237.894
If we take 76 away from 90, 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.

On to step 10:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 16237.8947
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
19 goes into 70 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 16237.89473
Subtracting 57 from 70 leaves us 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.

Step 12:
If we divide 130 by 19, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16237.894736
Subtracting 114 from 130 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.

Let's proceed to step 13:
If we divide 160 by 19, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 16237.8947368
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
When dividing 80 by 19, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 16237.89473684
Subtract 76 from 80 to 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.

Our division results in 16237.89473684 with a remaining 4e-09.
