We look at the division of 408280 by 19 
Let's see how many times 19 fits into 408280.

Advancing to step 1:
19 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 19

Moving on to step 2:
40 divided by 19 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 38 from 40 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 19

Step 3:
28 divided by 19 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 19 from 28 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 19

Advancing to step 4:
When dividing 92 by 19, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 214.0
If we subtract 76 from 92, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 19

Step 5:
19 goes into 168 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2148.0
Subtract 152 from 168 to get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 19

Moving on to step 6:
19 goes into 160 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 21488.0
Deduct 152 from 160 and we're left 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.

Going ahead to step 7:
When dividing 80 by 19, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 21488.4
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.

Advancing to step 8:
40 divided by 19 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 21488.42
If we subtract 38 from 40, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
20 divided by 19 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 21488.421
Deduct 19 from 20 and we're left 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 10:
10 divided by 19 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21488.421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 19, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 21488.42105
If we subtract 95 from 100, we get 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 12:
50 divided by 19 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 21488.421052
Subtract 38 from 50 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 19 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 21488.4210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
19 goes into 60 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 21488.42105263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 21488.42105263 and a remainder of 3e-09.
