We look at the division of 729441 by 19 
We want to figure out the number of times 729441 can be divided by 19.

Step 1:
When dividing 7 by 19, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 19

Let's proceed to step 2:
72 divided by 19 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 57 from 72 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 19

Step 3:
159 divided by 19 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 152 from 159 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 19

Moving on to step 4:
19 can be fit into 74 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 383.0
Subtract 57 from 74 to get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 19

Advancing to step 5:
If we divide 174 by 19, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 3839.0
Subtract 171 from 174 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 19

Step 6:
If we divide 31 by 19, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 38391.0
Subtract 19 from 31 to 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.

On to step 7:
When dividing 120 by 19, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 38391.6
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 19, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 38391.63
If we take 57 away from 60, we end up 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.

Let's proceed to step 9:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 38391.631
If we take 19 away from 30, we end up 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.

Let's proceed to step 10:
When dividing 110 by 19, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 38391.6315
Subtracting 95 from 110 leaves us 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.

Moving on to step 11:
If we divide 150 by 19, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 38391.63157
If we take 133 away from 150, we end up with 17.
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 12:
19 goes into 170 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 38391.631578
Subtract 152 from 170 to get 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 13:
180 divided by 19 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 38391.6315789
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.

Going ahead to step 14:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 38391.63157894
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 final result is 38391.63157894 with a remainder of 1.4e-08.
