729009 ÷ 28 
We're looking to find how many times 28 goes into 729009.

On to step 1:
7 divided by 28 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 28

Going ahead to step 2:
72 divided by 28 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 56 from 72 and we're left with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 28

Going ahead to step 3:
28 can be fit into 169 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 168 from 169 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 28

Let's proceed to step 4:
10 divided by 28 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 260.0
If we subtract 0 from 10, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 28

On to step 5:
28 goes into 100 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 2603.0
Subtracting 84 from 100 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 28

Moving on to step 6:
The number 28 fits into 169 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 26036.0
If we subtract 168 from 169, we 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.

On to step 7:
10 divided by 28 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 26036.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
28 goes into 100 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 26036.03
If we subtract 84 from 100, 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.

Let's proceed to step 9:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 26036.035
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 26036.0357
If we subtract 196 from 200, we 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.

Advancing to step 11:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 26036.03571
If we subtract 28 from 40, 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.

Moving on to step 12:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 26036.035714
If we take 112 away from 120, 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.

Moving on to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 26036.0357142
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 26036.03571428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 26036.03571428, with a leftover of 1.6e-08.
