315378 ÷ 28 
Let's see how many times 28 fits into 315378.

On to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 28

Advancing to step 2:
28 can be fit into 31 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 28 from 31, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 28

Step 3:
If we divide 35 by 28, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 7 after subtracting 28 from 35.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 28

Moving on to step 4:
If we divide 73 by 28, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 17 after subtracting 56 from 73.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 28

Going ahead to step 5:
When dividing 177 by 28, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 1126.0
Deduct 168 from 177 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 28

Moving on to step 6:
28 can be fit into 98 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 11263.0
Deduct 84 from 98 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
28 can be fit into 140 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11263.5
If we take 140 away from 140, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 28, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11263.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11263.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11263.5 with a remainder of 0.0.
