80309028 ÷ 729 
Let's see how many times 729 fits into 80309028.

Let's proceed to step 1:
8 divided by 729 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 729

On to step 2:
729 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 729

Advancing to step 3:
The number 729 fits into 803 1 times, leaving a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 729 from 803, we get 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 729

On to step 4:
The number 729 fits into 740 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 729 away from 740, we end up with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 729

Step 5:
119 divided by 729 is 0 with a remainder of 119.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtract 0 from 119 to get 119.
Include the next digit (0) from the dividend after 119, then repeat: 1190 / 729

Let's proceed to step 6:
729 can be fit into 1190 1 times, resulting in a remainder of 461.
The next digit of our result is 1. 
Result so far: 1101.0
If we subtract 729 from 1190, we get 461.
Bring next digit (2) of the dividend behind the 461 and repeat the process: 4612 / 729

On to step 7:
The number 729 fits into 4612 6 times, leaving a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 11016.0
Subtract 4374 from 4612 to get 238.
Include the next digit (8) from the dividend after 238, then repeat: 2388 / 729

Going ahead to step 8:
2388 divided by 729 is 3 with a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 110163.0
Deduct 2187 from 2388 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 9:
729 goes into 2010 2 times with a remainder of 552.
The next digit of our result is 2. 
Result so far: 110163.2
Subtract 1458 from 2010 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 10:
The number 729 fits into 5520 7 times, leaving a remainder of 417.
Use 7 as the next digit of our solution. 
Result so far: 110163.27
If we subtract 5103 from 5520, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 11:
The number 729 fits into 4170 5 times, leaving a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 110163.275
Subtracting 3645 from 4170 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 12:
729 goes into 5250 7 times with a remainder of 147.
The next digit of our result is 7. 
Result so far: 110163.2757
Deduct 5103 from 5250 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 13:
When dividing 1470 by 729, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 110163.27572
Subtracting 1458 from 1470 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
If we divide 120 by 729, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 110163.27572
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
729 goes into 1200 1 times with a remainder of 471.
Record the quotient 1 as the next digit in the result. 
Result so far: 110163.2757201
Subtracting 729 from 1200 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 16:
4710 divided by 729 is 6 with a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 110163.27572016
If we subtract 4374 from 4710, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The quotient of the division is 110163.27572016, and the remainder is 3.36e-07.
