We look at the division of 42301439 by 728 
We're looking to find how many times 728 goes into 42301439.

Step 1:
The number 728 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 728

Advancing to step 2:
42 divided by 728 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 728

Step 3:
If we divide 423 by 728, we get 0 and a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 423 leaves us with 423.
Append the next digit (0) from the dividend to 423 and continue with: 4230 / 728

Step 4:
When dividing 4230 by 728, we get 5 with a remainder of 590.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 3640 away from 4230, we end up with 590.
Include the next digit (1) from the dividend after 590, then repeat: 5901 / 728

Step 5:
728 goes into 5901 8 times with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we subtract 5824 from 5901, we get 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 728

Advancing to step 6:
When dividing 774 by 728, we get 1 with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 581.0
If we take 728 away from 774, we end up with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 728

Moving on to step 7:
463 divided by 728 is 0 with a remainder of 463.
The number 0 becomes the next digit in our result. 
Result so far: 5810.0
The remainder is 463 after subtracting 0 from 463.
Include the next digit (9) from the dividend after 463, then repeat: 4639 / 728

Step 8:
728 goes into 4639 6 times with a remainder of 271.
Use 6 as the next digit of our solution. 
Result so far: 58106.0
If we subtract 4368 from 4639, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
728 can be fit into 2710 3 times, resulting in a remainder of 526.
Write down 3 as next digit of the result. 
Result so far: 58106.3
If we take 2184 away from 2710, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 10:
728 can be fit into 5260 7 times, resulting in a remainder of 164.
The next digit of our result is 7. 
Result so far: 58106.37
Subtract 5096 from 5260 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
728 can be fit into 1640 2 times, resulting in a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 58106.372
Subtract 1456 from 1640 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
If we divide 1840 by 728, we get 2 and a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 58106.3722
The remainder is 384 after subtracting 1456 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

In conclusion, the division gives 58106.3722 with a balance of 0.00384.
