We look at the division of 402647 by 19 
Let's see how many times 19 fits into 402647.

On to step 1:
19 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 19

Going ahead to step 2:
19 goes into 40 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 38 from 40 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 19

Moving on to step 3:
19 can be fit into 22 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 3 after subtracting 19 from 22.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 19

Advancing to step 4:
36 divided by 19 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 211.0
If we subtract 19 from 36, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 19

Advancing to step 5:
19 goes into 174 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 2119.0
Subtracting 171 from 174 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 19

Advancing to step 6:
37 divided by 19 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 21191.0
If we subtract 19 from 37, 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.

Step 7:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 21191.9
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
If we divide 90 by 19, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 21191.94
Subtracting 76 from 90 leaves us 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.

Moving on to step 9:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 21191.947
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.

Advancing to step 10:
19 goes into 70 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 21191.9473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
19 goes into 130 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 21191.94736
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.

Step 12:
When dividing 160 by 19, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 21191.947368
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 13:
19 goes into 80 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 21191.9473684
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.

On to step 14:
If we divide 40 by 19, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 21191.94736842
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.

Our division results in 21191.94736842 with a remaining 2e-09.
