54284690 ÷ 728 
Let's see how many times 728 fits into 54284690.

Step 1:
728 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 728

Moving on to step 2:
54 divided by 728 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 728

Moving on to step 3:
The number 728 fits into 542 0 times, leaving a remainder of 542.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 542, we end up with 542.
Grab the next digit (8) from the dividend, add it to 542, then carry on: 5428 / 728

Advancing to step 4:
If we divide 5428 by 728, we get 7 and a remainder of 332.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5096 from 5428, we get 332.
Include the next digit (4) from the dividend after 332, then repeat: 3324 / 728

Moving on to step 5:
3324 divided by 728 is 4 with a remainder of 412.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 2912 from 3324 and we're left with 412.
Grab the next digit (6) from the dividend, add it to 412, then carry on: 4126 / 728

Advancing to step 6:
728 goes into 4126 5 times with a remainder of 486.
Use 5 as the next digit of our solution. 
Result so far: 745.0
If we subtract 3640 from 4126, we get 486.
Bring next digit (9) of the dividend behind the 486 and repeat the process: 4869 / 728

Advancing to step 7:
728 can be fit into 4869 6 times, resulting in a remainder of 501.
Use 6 as the next digit of our solution. 
Result so far: 7456.0
Deduct 4368 from 4869 and we're left with 501.
Include the next digit (0) from the dividend after 501, then repeat: 5010 / 728

Step 8:
When dividing 5010 by 728, we get 6 with a remainder of 642.
Put 6 as the next digit of the answer. 
Result so far: 74566.0
The remainder is 642 after subtracting 4368 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Going ahead to step 9:
The number 728 fits into 6420 8 times, leaving a remainder of 596.
Put 8 as the next digit of the answer. 
Result so far: 74566.8
Subtracting 5824 from 6420 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 10:
728 can be fit into 5960 8 times, resulting in a remainder of 136.
The next digit of our result is 8. 
Result so far: 74566.88
If we take 5824 away from 5960, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 74566.88 with a remainder of 0.136.
