We're dividing 12928743 by 729 
Our goal is to divide 12928743 by 729.

Step 1:
729 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 729

Moving on to step 2:
The number 729 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 729

Moving on to step 3:
129 divided by 729 is 0 with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Include the next digit (2) from the dividend after 129, then repeat: 1292 / 729

Advancing to step 4:
If we divide 1292 by 729, we get 1 and a remainder of 563.
The next digit of our result is 1. 
Result so far: 1.0
If we take 729 away from 1292, we end up with 563.
Fetch the next digit (8) from the dividend, attach it to 563 and continue: 5638 / 729

Going ahead to step 5:
729 goes into 5638 7 times with a remainder of 535.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 5103 away from 5638, we end up with 535.
Fetch the next digit (7) from the dividend, attach it to 535 and continue: 5357 / 729

Moving on to step 6:
729 goes into 5357 7 times with a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we subtract 5103 from 5357, we get 254.
Take the next digit (4) from the dividend and append it to 254, then repeat: 2544 / 729

Moving on to step 7:
2544 divided by 729 is 3 with a remainder of 357.
Use 3 as the next digit of our solution. 
Result so far: 1773.0
Subtracting 2187 from 2544 leaves us with 357.
Grab the next digit (3) from the dividend, add it to 357, then carry on: 3573 / 729

Going ahead to step 8:
729 goes into 3573 4 times with a remainder of 657.
The number 4 becomes the next digit in our result. 
Result so far: 17734.0
Subtract 2916 from 3573 to get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

On to step 9:
729 can be fit into 6570 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 17734.9
Subtracting 6561 from 6570 leaves us 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 10:
729 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 17734.9
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
If we divide 900 by 729, we get 1 and a remainder of 171.
The next digit of our result is 1. 
Result so far: 17734.901
The remainder is 171 after subtracting 729 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 12:
If we divide 1710 by 729, we get 2 and a remainder of 252.
The next digit of our result is 2. 
Result so far: 17734.9012
The remainder is 252 after subtracting 1458 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
729 goes into 2520 3 times with a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 17734.90123
The remainder is 333 after subtracting 2187 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 14:
When dividing 3330 by 729, we get 4 with a remainder of 414.
Put 4 as the next digit of the answer. 
Result so far: 17734.901234
If we take 2916 away from 3330, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 15:
729 goes into 4140 5 times with a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 17734.9012345
Subtract 3645 from 4140 to get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 16:
When dividing 4950 by 729, we get 6 with a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 17734.90123456
The remainder is 576 after subtracting 4374 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final outcome is 17734.90123456, with a leftover of 5.76e-07.
