408508 divided by 19 
We want to figure out the number of times 408508 can be divided by 19.

Advancing to step 1:
19 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 19

On to step 2:
19 goes into 40 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 38 away from 40, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 19

Moving on to step 3:
The number 19 fits into 28 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 19 from 28, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 19

Step 4:
The number 19 fits into 95 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 215.0
If we take 95 away from 95, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 19

Advancing to step 5:
When dividing 0 by 19, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2150.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 19

On to step 6:
If we divide 8 by 19, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 21500.0
Subtracting 0 from 8 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.

Step 7:
If we divide 80 by 19, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 21500.4
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.

Let's proceed to step 8:
When dividing 40 by 19, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 21500.42
Subtracting 38 from 40 leaves us 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.

Going ahead to step 9:
19 goes into 20 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 21500.421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
The number 19 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21500.421
Subtract 0 from 10 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.

Moving on to step 11:
When dividing 100 by 19, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21500.42105
Subtracting 95 from 100 leaves us 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.

Advancing to step 12:
If we divide 50 by 19, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 21500.421052
If we subtract 38 from 50, we 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.

Step 13:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 21500.4210526
Subtracting 114 from 120 leaves us 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.

Moving on to step 14:
60 divided by 19 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 21500.42105263
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.

After the division, we end up with 21500.42105263 and a remainder of 3e-09.
