28306980 divided by 728 
We want to figure out the number of times 28306980 can be divided by 728.

Let's proceed to step 1:
728 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 728

Going ahead to step 2:
728 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 728

Let's proceed to step 3:
When dividing 283 by 728, we get 0 with a remainder of 283.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 283, we end up with 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 728

Advancing to step 4:
If we divide 2830 by 728, we get 3 and a remainder of 646.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2184 away from 2830, we end up with 646.
Fetch the next digit (6) from the dividend, attach it to 646 and continue: 6466 / 728

Going ahead to step 5:
728 goes into 6466 8 times with a remainder of 642.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 5824 from 6466, we get 642.
Take the next digit (9) from the dividend and append it to 642, then repeat: 6429 / 728

Let's proceed to step 6:
If we divide 6429 by 728, we get 8 and a remainder of 605.
Write down 8 as next digit of the result. 
Result so far: 388.0
The remainder is 605 after subtracting 5824 from 6429.
Append the next digit (8) from the dividend to 605 and continue with: 6058 / 728

Step 7:
If we divide 6058 by 728, we get 8 and a remainder of 234.
Put 8 as the next digit of the answer. 
Result so far: 3888.0
The remainder is 234 after subtracting 5824 from 6058.
Fetch the next digit (0) from the dividend, attach it to 234 and continue: 2340 / 728

Let's proceed to step 8:
728 can be fit into 2340 3 times, resulting in a remainder of 156.
The number 3 becomes the next digit in our result. 
Result so far: 38883.0
Subtracting 2184 from 2340 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
1560 divided by 728 is 2 with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 38883.2
If we subtract 1456 from 1560, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
728 can be fit into 1040 1 times, resulting in a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 38883.21
Deduct 728 from 1040 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 11:
The number 728 fits into 3120 4 times, leaving a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 38883.214
If we take 2912 away from 3120, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
2080 divided by 728 is 2 with a remainder of 624.
Use 2 as the next digit of our solution. 
Result so far: 38883.2142
Subtracting 1456 from 2080 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 13:
728 goes into 6240 8 times with a remainder of 416.
The next digit of our result is 8. 
Result so far: 38883.21428
Deduct 5824 from 6240 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
If we divide 4160 by 728, we get 5 and a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 38883.214285
Deduct 3640 from 4160 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 15:
728 goes into 5200 7 times with a remainder of 104.
Record the quotient 7 as the next digit in the result. 
Result so far: 38883.2142857
If we take 5096 away from 5200, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 16:
When dividing 1040 by 728, we get 1 with a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 38883.21428571
Deduct 728 from 1040 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 38883.21428571 with a remaining 3.12e-07.
