8749438 ÷ 729 
Let's see how many times 729 fits into 8749438.

On to step 1:
The number 729 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 729

On to step 2:
87 divided by 729 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Bring next digit (4) of the dividend behind the 87 and repeat the process: 874 / 729

Let's proceed to step 3:
729 goes into 874 1 times with a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 145 after subtracting 729 from 874.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 729

Advancing to step 4:
The number 729 fits into 1459 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1458 from 1459 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 729

On to step 5:
729 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 14, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 729

Let's proceed to step 6:
The number 729 fits into 143 0 times, leaving a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 1200.0
Subtract 0 from 143 to get 143.
Bring next digit (8) of the dividend behind the 143 and repeat the process: 1438 / 729

On to step 7:
When dividing 1438 by 729, we get 1 with a remainder of 709.
The next digit of our result is 1. 
Result so far: 12001.0
Subtract 729 from 1438 to get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Moving on to step 8:
729 goes into 7090 9 times with a remainder of 529.
The next digit of our result is 9. 
Result so far: 12001.9
The remainder is 529 after subtracting 6561 from 7090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 9:
729 can be fit into 5290 7 times, resulting in a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 12001.97
Deduct 5103 from 5290 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 10:
1870 divided by 729 is 2 with a remainder of 412.
Record the quotient 2 as the next digit in the result. 
Result so far: 12001.972
If we subtract 1458 from 1870, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 11:
The number 729 fits into 4120 5 times, leaving a remainder of 475.
The number 5 becomes the next digit in our result. 
Result so far: 12001.9725
Deduct 3645 from 4120 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 12:
729 can be fit into 4750 6 times, resulting in a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 12001.97256
If we subtract 4374 from 4750, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 13:
3760 divided by 729 is 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 12001.972565
Subtract 3645 from 3760 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 14:
729 goes into 1150 1 times with a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 12001.9725651
Deduct 729 from 1150 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 15:
729 can be fit into 4210 5 times, resulting in a remainder of 565.
Use 5 as the next digit of our solution. 
Result so far: 12001.97256515
The remainder is 565 after subtracting 3645 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

The final outcome is 12001.97256515, with a leftover of 5.65e-07.
