We're dividing 28717253 by 280 
We want to figure out the number of times 28717253 can be divided by 280.

Moving on to step 1:
280 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 280

Let's proceed to step 2:
28 divided by 280 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 280

Advancing to step 3:
280 goes into 287 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 280 from 287, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 280

Let's proceed to step 4:
If we divide 71 by 280, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 71 to get 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 280

Let's proceed to step 5:
When dividing 717 by 280, we get 2 with a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 560 from 717 leaves us with 157.
Bring next digit (2) of the dividend behind the 157 and repeat the process: 1572 / 280

On to step 6:
280 goes into 1572 5 times with a remainder of 172.
Put 5 as the next digit of the answer. 
Result so far: 1025.0
If we take 1400 away from 1572, we end up with 172.
Take the next digit (5) from the dividend and append it to 172, then repeat: 1725 / 280

Going ahead to step 7:
1725 divided by 280 is 6 with a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 10256.0
The remainder is 45 after subtracting 1680 from 1725.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 280

Moving on to step 8:
If we divide 453 by 280, we get 1 and a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 102561.0
Subtract 280 from 453 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 9:
When dividing 1730 by 280, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 102561.6
If we take 1680 away from 1730, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
280 goes into 500 1 times with a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 102561.61
Deduct 280 from 500 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
280 goes into 2200 7 times with a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 102561.617
Subtracting 1960 from 2200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
The next digit of our result is 8. 
Result so far: 102561.6178
Deduct 2240 from 2400 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
1600 divided by 280 is 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 102561.61785
If we take 1400 away from 1600, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
2000 divided by 280 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 102561.617857
Subtract 1960 from 2000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
When dividing 400 by 280, we get 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 102561.6178571
Deduct 280 from 400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
The number 280 fits into 1200 4 times, leaving a remainder of 80.
The next digit of our result is 4. 
Result so far: 102561.61785714
Subtracting 1120 from 1200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 102561.61785714 with a remainder of 8e-08.
