We're dividing 820990 by 19 
We want to figure out the number of times 820990 can be divided by 19.

Step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 19

Advancing to step 2:
19 can be fit into 82 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 6 after subtracting 76 from 82.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 19

Moving on to step 3:
The number 19 fits into 60 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 57 from 60 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 19

Advancing to step 4:
19 can be fit into 39 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
Subtract 38 from 39 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 19

Moving on to step 5:
When dividing 19 by 19, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 4321.0
Subtract 19 from 19 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 19

On to step 6:
If we divide 0 by 19, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43210.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 19, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43210.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 19 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43210.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 43210.0, and the remainder is 0.0.
