We're dividing 4839987 by 728 
We're looking to find how many times 728 goes into 4839987.

Step 1:
If we divide 4 by 728, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 728

Going ahead to step 2:
When dividing 48 by 728, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 728

Step 3:
When dividing 483 by 728, we get 0 with a remainder of 483.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 483 and we're left with 483.
Bring next digit (9) of the dividend behind the 483 and repeat the process: 4839 / 728

Advancing to step 4:
When dividing 4839 by 728, we get 6 with a remainder of 471.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 4368 away from 4839, we end up with 471.
Take the next digit (9) from the dividend and append it to 471, then repeat: 4719 / 728

Going ahead to step 5:
728 goes into 4719 6 times with a remainder of 351.
The next digit of our result is 6. 
Result so far: 66.0
Subtract 4368 from 4719 to get 351.
Grab the next digit (8) from the dividend, add it to 351, then carry on: 3518 / 728

On to step 6:
The number 728 fits into 3518 4 times, leaving a remainder of 606.
Put 4 as the next digit of the answer. 
Result so far: 664.0
Deduct 2912 from 3518 and we're left with 606.
Append the next digit (7) from the dividend to 606 and continue with: 6067 / 728

Step 7:
When dividing 6067 by 728, we get 8 with a remainder of 243.
Use 8 as the next digit of our solution. 
Result so far: 6648.0
If we subtract 5824 from 6067, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 8:
When dividing 2430 by 728, we get 3 with a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 6648.3
If we subtract 2184 from 2430, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 9:
The number 728 fits into 2460 3 times, leaving a remainder of 276.
Put 3 as the next digit of the answer. 
Result so far: 6648.33
The remainder is 276 after subtracting 2184 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final outcome is 6648.33, with a leftover of 0.276.
