728145 ÷ 19 
We want to figure out the number of times 728145 can be divided by 19.

Going ahead to step 1:
19 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 19

Going ahead to step 2:
72 divided by 19 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 57 from 72 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 19

On to step 3:
19 goes into 158 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 152 from 158 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 19

Advancing to step 4:
The number 19 fits into 61 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 383.0
Subtracting 57 from 61 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 19

Step 5:
When dividing 44 by 19, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 3832.0
The remainder is 6 after subtracting 38 from 44.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 19

Advancing to step 6:
If we divide 65 by 19, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 38323.0
Deduct 57 from 65 and we're left 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.

Step 7:
19 goes into 80 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 38323.4
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 38323.42
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 19, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 38323.421
Deduct 19 from 20 and we're left 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.

On to step 10:
If we divide 10 by 19, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 38323.421
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.

Moving on to step 11:
If we divide 100 by 19, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 38323.42105
Deduct 95 from 100 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.

Going ahead to step 12:
50 divided by 19 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 38323.421052
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 38323.4210526
If we subtract 114 from 120, we 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.

Step 14:
19 goes into 60 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 38323.42105263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 38323.42105263, with a leftover of 3e-09.
