18816959 ÷ 728 
We want to divide 18816959 by 728.

Moving on to step 1:
When dividing 1 by 728, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 728

On to step 2:
728 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 728

Moving on to step 3:
188 divided by 728 is 0 with a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Include the next digit (1) from the dividend after 188, then repeat: 1881 / 728

Going ahead to step 4:
If we divide 1881 by 728, we get 2 and a remainder of 425.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1456 from 1881 leaves us with 425.
Bring next digit (6) of the dividend behind the 425 and repeat the process: 4256 / 728

Let's proceed to step 5:
4256 divided by 728 is 5 with a remainder of 616.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 3640 from 4256 to get 616.
Append the next digit (9) from the dividend to 616 and continue with: 6169 / 728

Moving on to step 6:
6169 divided by 728 is 8 with a remainder of 345.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
Subtracting 5824 from 6169 leaves us with 345.
Fetch the next digit (5) from the dividend, attach it to 345 and continue: 3455 / 728

Step 7:
When dividing 3455 by 728, we get 4 with a remainder of 543.
Put 4 as the next digit of the answer. 
Result so far: 2584.0
The remainder is 543 after subtracting 2912 from 3455.
Fetch the next digit (9) from the dividend, attach it to 543 and continue: 5439 / 728

Going ahead to step 8:
If we divide 5439 by 728, we get 7 and a remainder of 343.
The number 7 becomes the next digit in our result. 
Result so far: 25847.0
If we take 5096 away from 5439, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 9:
When dividing 3430 by 728, we get 4 with a remainder of 518.
The number 4 becomes the next digit in our result. 
Result so far: 25847.4
Deduct 2912 from 3430 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 10:
The number 728 fits into 5180 7 times, leaving a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 25847.47
If we subtract 5096 from 5180, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
If we divide 840 by 728, we get 1 and a remainder of 112.
The number 1 becomes the next digit in our result. 
Result so far: 25847.471
Subtract 728 from 840 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 12:
When dividing 1120 by 728, we get 1 with a remainder of 392.
Write down 1 as next digit of the result. 
Result so far: 25847.4711
The remainder is 392 after subtracting 728 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final result is 25847.4711 with a remainder of 0.00392.
