28256428 ÷ 723 
We want to figure out the number of times 28256428 can be divided by 723.

On to step 1:
2 divided by 723 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 723

On to step 2:
When dividing 28 by 723, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 723

On to step 3:
When dividing 282 by 723, we get 0 with a remainder of 282.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 282, we end up with 282.
Bring next digit (5) of the dividend behind the 282 and repeat the process: 2825 / 723

Step 4:
The number 723 fits into 2825 3 times, leaving a remainder of 656.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2169 from 2825 and we're left with 656.
Take the next digit (6) from the dividend and append it to 656, then repeat: 6566 / 723

Let's proceed to step 5:
If we divide 6566 by 723, we get 9 and a remainder of 59.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 6507 from 6566 leaves us with 59.
Grab the next digit (4) from the dividend, add it to 59, then carry on: 594 / 723

Let's proceed to step 6:
723 goes into 594 0 times with a remainder of 594.
Write down 0 as next digit of the result. 
Result so far: 390.0
The remainder is 594 after subtracting 0 from 594.
Append the next digit (2) from the dividend to 594 and continue with: 5942 / 723

Going ahead to step 7:
723 goes into 5942 8 times with a remainder of 158.
Put 8 as the next digit of the answer. 
Result so far: 3908.0
The remainder is 158 after subtracting 5784 from 5942.
Include the next digit (8) from the dividend after 158, then repeat: 1588 / 723

Moving on to step 8:
723 goes into 1588 2 times with a remainder of 142.
The next digit of our result is 2. 
Result so far: 39082.0
Subtracting 1446 from 1588 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 9:
1420 divided by 723 is 1 with a remainder of 697.
Write down 1 as next digit of the result. 
Result so far: 39082.1
Deduct 723 from 1420 and we're left with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Let's proceed to step 10:
When dividing 6970 by 723, we get 9 with a remainder of 463.
Write down 9 as next digit of the result. 
Result so far: 39082.19
If we subtract 6507 from 6970, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Step 11:
723 can be fit into 4630 6 times, resulting in a remainder of 292.
The next digit of our result is 6. 
Result so far: 39082.196
Deduct 4338 from 4630 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 12:
723 can be fit into 2920 4 times, resulting in a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 39082.1964
If we subtract 2892 from 2920, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
723 goes into 280 0 times with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 39082.1964
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
723 goes into 2800 3 times with a remainder of 631.
The number 3 becomes the next digit in our result. 
Result so far: 39082.196403
Subtract 2169 from 2800 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 15:
If we divide 6310 by 723, we get 8 and a remainder of 526.
The number 8 becomes the next digit in our result. 
Result so far: 39082.1964038
The remainder is 526 after subtracting 5784 from 6310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 16:
When dividing 5260 by 723, we get 7 with a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 39082.19640387
Deduct 5061 from 5260 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The final result is 39082.19640387 with a remainder of 1.99e-07.
