53124818 ÷ 729 
Our goal is to divide 53124818 by 729.

Step 1:
5 divided by 729 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 729

Step 2:
729 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 729

Going ahead to step 3:
If we divide 531 by 729, we get 0 and a remainder of 531.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 531 to get 531.
Fetch the next digit (2) from the dividend, attach it to 531 and continue: 5312 / 729

Let's proceed to step 4:
When dividing 5312 by 729, we get 7 with a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5103 from 5312 leaves us with 209.
Take the next digit (4) from the dividend and append it to 209, then repeat: 2094 / 729

Moving on to step 5:
729 can be fit into 2094 2 times, resulting in a remainder of 636.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 1458 from 2094 to get 636.
Take the next digit (8) from the dividend and append it to 636, then repeat: 6368 / 729

Going ahead to step 6:
729 goes into 6368 8 times with a remainder of 536.
Write down 8 as next digit of the result. 
Result so far: 728.0
If we subtract 5832 from 6368, we get 536.
Include the next digit (1) from the dividend after 536, then repeat: 5361 / 729

Step 7:
When dividing 5361 by 729, we get 7 with a remainder of 258.
Record the quotient 7 as the next digit in the result. 
Result so far: 7287.0
Deduct 5103 from 5361 and we're left with 258.
Include the next digit (8) from the dividend after 258, then repeat: 2588 / 729

Moving on to step 8:
2588 divided by 729 is 3 with a remainder of 401.
Put 3 as the next digit of the answer. 
Result so far: 72873.0
The remainder is 401 after subtracting 2187 from 2588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 9:
729 goes into 4010 5 times with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 72873.5
The remainder is 365 after subtracting 3645 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 10:
If we divide 3650 by 729, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 72873.55
If we subtract 3645 from 3650, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 72873.55 with a remainder of 0.005.
