72169573 ÷ 729 
Our goal is to divide 72169573 by 729.

Going ahead to step 1:
729 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 729

Going ahead to step 2:
72 divided by 729 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 729

Advancing to step 3:
729 can be fit into 721 0 times, resulting in a remainder of 721.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 721 to get 721.
Take the next digit (6) from the dividend and append it to 721, then repeat: 7216 / 729

On to step 4:
When dividing 7216 by 729, we get 9 with a remainder of 655.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 655 after subtracting 6561 from 7216.
Append the next digit (9) from the dividend to 655 and continue with: 6559 / 729

Step 5:
If we divide 6559 by 729, we get 8 and a remainder of 727.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 5832 from 6559 to get 727.
Fetch the next digit (5) from the dividend, attach it to 727 and continue: 7275 / 729

Moving on to step 6:
If we divide 7275 by 729, we get 9 and a remainder of 714.
Record the quotient 9 as the next digit in the result. 
Result so far: 989.0
Deduct 6561 from 7275 and we're left with 714.
Bring next digit (7) of the dividend behind the 714 and repeat the process: 7147 / 729

Let's proceed to step 7:
7147 divided by 729 is 9 with a remainder of 586.
The number 9 becomes the next digit in our result. 
Result so far: 9899.0
Subtract 6561 from 7147 to get 586.
Fetch the next digit (3) from the dividend, attach it to 586 and continue: 5863 / 729

Going ahead to step 8:
The number 729 fits into 5863 8 times, leaving a remainder of 31.
The next digit of our result is 8. 
Result so far: 98998.0
Deduct 5832 from 5863 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 729 fits into 310 0 times, leaving a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 98998.0
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
The number 729 fits into 3100 4 times, leaving a remainder of 184.
The next digit of our result is 4. 
Result so far: 98998.04
The remainder is 184 after subtracting 2916 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 11:
If we divide 1840 by 729, we get 2 and a remainder of 382.
The next digit of our result is 2. 
Result so far: 98998.042
If we subtract 1458 from 1840, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 12:
729 goes into 3820 5 times with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 98998.0425
The remainder is 175 after subtracting 3645 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 13:
729 can be fit into 1750 2 times, resulting in a remainder of 292.
Put 2 as the next digit of the answer. 
Result so far: 98998.04252
If we subtract 1458 from 1750, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 14:
2920 divided by 729 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 98998.042524
Subtract 2916 from 2920 to 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 15:
729 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 98998.042524
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
400 divided by 729 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 98998.042524
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 98998.042524 with a balance of 4e-07.
