We look at the division of 721009 by 19 
We want to divide 721009 by 19.

Going ahead to step 1:
When dividing 7 by 19, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 19

Going ahead to step 2:
19 can be fit into 72 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 57 from 72, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 19

On to step 3:
19 goes into 151 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 133 from 151 and we're left with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 19

Moving on to step 4:
180 divided by 19 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 379.0
The remainder is 9 after subtracting 171 from 180.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 19

Going ahead to step 5:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3794.0
Deduct 76 from 90 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 19

On to step 6:
The number 19 fits into 149 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 37947.0
If we subtract 133 from 149, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 37947.8
If we take 152 away from 160, we end up 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.

Going ahead to step 8:
80 divided by 19 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 37947.84
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.

Let's proceed to step 9:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 37947.842
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 37947.8421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 37947.8421
Subtracting 0 from 10 leaves us 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.

Step 12:
19 goes into 100 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 37947.842105
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 37947.8421052
Subtracting 38 from 50 leaves us 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.

Advancing to step 14:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 37947.84210526
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.

The quotient of the division is 37947.84210526, and the remainder is 6e-09.
