724171 ÷ 19 
Our goal is to divide 724171 by 19.

Step 1:
The number 19 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 19

Let's proceed to step 2:
19 can be fit into 72 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 57 from 72, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 19

Moving on to step 3:
154 divided by 19 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 152 from 154 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 19

On to step 4:
19 goes into 21 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 381.0
Subtract 19 from 21 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 19

Going ahead to step 5:
The number 19 fits into 27 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 3811.0
Subtract 19 from 27 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 19

Moving on to step 6:
19 can be fit into 81 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 38114.0
Deduct 76 from 81 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 19 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 38114.2
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.

Going ahead to step 8:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 38114.26
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 19, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 38114.263
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
When dividing 30 by 19, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 38114.2631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 38114.26315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
If we divide 150 by 19, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 38114.263157
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 38114.2631578
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.

Let's proceed to step 14:
If we divide 180 by 19, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 38114.26315789
If we take 171 away from 180, we end up 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.

The quotient of the division is 38114.26315789, and the remainder is 9e-09.
