42239315 divided by 729 
Our goal is to divide 42239315 by 729.

Moving on to step 1:
729 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 729

Advancing to step 2:
When dividing 42 by 729, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 729

Going ahead to step 3:
729 can be fit into 422 0 times, resulting in a remainder of 422.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 422 and we're left with 422.
Append the next digit (3) from the dividend to 422 and continue with: 4223 / 729

Moving on to step 4:
The number 729 fits into 4223 5 times, leaving a remainder of 578.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3645 from 4223 and we're left with 578.
Fetch the next digit (9) from the dividend, attach it to 578 and continue: 5789 / 729

Step 5:
5789 divided by 729 is 7 with a remainder of 686.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 686 after subtracting 5103 from 5789.
Bring next digit (3) of the dividend behind the 686 and repeat the process: 6863 / 729

Step 6:
729 goes into 6863 9 times with a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 579.0
If we subtract 6561 from 6863, we get 302.
Include the next digit (1) from the dividend after 302, then repeat: 3021 / 729

Advancing to step 7:
3021 divided by 729 is 4 with a remainder of 105.
Put 4 as the next digit of the answer. 
Result so far: 5794.0
If we take 2916 away from 3021, we end up with 105.
Grab the next digit (5) from the dividend, add it to 105, then carry on: 1055 / 729

Going ahead to step 8:
1055 divided by 729 is 1 with a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 57941.0
If we subtract 729 from 1055, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 9:
If we divide 3260 by 729, we get 4 and a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 57941.4
If we take 2916 away from 3260, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
3440 divided by 729 is 4 with a remainder of 524.
The next digit of our result is 4. 
Result so far: 57941.44
Deduct 2916 from 3440 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final outcome is 57941.44, with a leftover of 0.524.
