We look at the division of 99021 by 19 
Let's see how many times 19 fits into 99021.

Let's proceed to step 1:
If we divide 9 by 19, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 19

Going ahead to step 2:
The number 19 fits into 99 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
If we take 95 away from 99, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 19

Let's proceed to step 3:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 38 from 40 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 19

Step 4:
If we divide 22 by 19, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 521.0
If we subtract 19 from 22, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 19

On to step 5:
19 can be fit into 31 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 5211.0
The remainder is 12 after subtracting 19 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 5211.6
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 5211.63
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
30 divided by 19 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 5211.631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 5211.6315
Deduct 95 from 110 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 19 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 5211.63157
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
When dividing 170 by 19, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 5211.631578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
The number 19 fits into 180 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 5211.6315789
Deduct 171 from 180 and we're left 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.

On to step 13:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 5211.63157894
Deduct 76 from 90 and we're left 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.

The quotient of the division is 5211.63157894, and the remainder is 1.4e-08.
