We look at the division of 405382 by 19 
Let's see how many times 19 fits into 405382.

Going ahead to step 1:
19 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 19

Moving on to step 2:
40 divided by 19 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 38 from 40, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 19

Moving on to step 3:
When dividing 25 by 19, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 19 from 25 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 19

Moving on to step 4:
19 can be fit into 63 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 213.0
Deduct 57 from 63 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 19

Let's proceed to step 5:
When dividing 68 by 19, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 2133.0
The remainder is 11 after subtracting 57 from 68.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 19

Let's proceed to step 6:
112 divided by 19 is 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 21335.0
Deduct 95 from 112 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 21335.8
If we subtract 152 from 170, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
When dividing 180 by 19, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 21335.89
Subtracting 171 from 180 leaves us with 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.
Record the quotient 4 as the next digit in the result. 
Result so far: 21335.894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 19, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 21335.8947
Deduct 133 from 140 and we're left 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.

Step 11:
70 divided by 19 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 21335.89473
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.

Advancing to step 12:
When dividing 130 by 19, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 21335.894736
If we take 114 away from 130, we end up 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.

On to step 13:
160 divided by 19 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 21335.8947368
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.

On to step 14:
The number 19 fits into 80 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 21335.89473684
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 21335.89473684 and a remainder of 4e-09.
