312303 divided by 4 
Our goal is to divide 312303 by 4.

Moving on to step 1:
If we divide 3 by 4, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 4

Advancing to step 2:
The number 4 fits into 31 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 28 from 31 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

Let's proceed to step 3:
32 divided by 4 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 32 from 32 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

On to step 4:
4 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

Step 5:
30 divided by 4 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7807.0
Subtracting 28 from 30 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

On to step 6:
If we divide 23 by 4, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 78075.0
Deduct 20 from 23 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 4 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 78075.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 78075.75
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 78075.75
The remainder is 0 after subtracting 0 from 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 10:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 78075.75
The remainder is 0 after subtracting 0 from 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 78075.75 with a remainder of 0.0.
