We look at the division of 28438782 by 310 
We want to figure out the number of times 28438782 can be divided by 310.

Step 1:
The number 310 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 310

Moving on to step 2:
310 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 310

Let's proceed to step 3:
310 can be fit into 284 0 times, resulting in a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Append the next digit (3) from the dividend to 284 and continue with: 2843 / 310

Let's proceed to step 4:
2843 divided by 310 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 2790 from 2843 leaves us with 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 310

Step 5:
538 divided by 310 is 1 with a remainder of 228.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Deduct 310 from 538 and we're left with 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 310

On to step 6:
If we divide 2287 by 310, we get 7 and a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 917.0
Subtract 2170 from 2287 to get 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 310

Advancing to step 7:
If we divide 1178 by 310, we get 3 and a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 9173.0
Deduct 930 from 1178 and we're left with 248.
Take the next digit (2) from the dividend and append it to 248, then repeat: 2482 / 310

Going ahead to step 8:
310 can be fit into 2482 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 91738.0
Subtracting 2480 from 2482 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
310 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 91738.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
310 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 91738.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 91738.0 and a remainder of 0.2.
