We look at the division of 392021 by 19 
We're looking to find how many times 19 goes into 392021.

Let's proceed to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 19

Step 2:
If we divide 39 by 19, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 38 from 39 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 19

Going ahead to step 3:
12 divided by 19 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 19

Step 4:
The number 19 fits into 120 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 206.0
Subtract 114 from 120 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 19

On to step 5:
The number 19 fits into 62 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 2063.0
If we subtract 57 from 62, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 19

Going ahead to step 6:
19 goes into 51 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 20632.0
Subtracting 38 from 51 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.

Going ahead to step 7:
19 can be fit into 130 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 20632.6
Deduct 114 from 130 and we're left 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 8:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 20632.68
Subtract 152 from 160 to get 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 9:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 20632.684
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.

Let's proceed to step 10:
If we divide 40 by 19, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 20632.6842
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.

Going ahead to step 11:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 20632.68421
Subtracting 19 from 20 leaves us 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 12:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 20632.68421
Deduct 0 from 10 and we're left with 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 13:
100 divided by 19 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 20632.6842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
19 goes into 50 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 20632.68421052
Deduct 38 from 50 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 20632.68421052 with a balance of 1.2e-08.
