312911 ÷ 4 
We want to divide 312911 by 4.

Going ahead 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.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Advancing to step 2:
The number 4 fits into 31 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 28 from 31, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Going ahead to step 3:
4 can be fit into 32 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 32 from 32 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

Step 4:
If we divide 9 by 4, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
Subtract 8 from 9 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 4

Step 5:
4 can be fit into 11 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 7822.0
If we subtract 8 from 11, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

On to step 6:
If we divide 31 by 4, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 78227.0
The remainder is 3 after subtracting 28 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 78227.7
Subtract 28 from 30 to 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.

Step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 78227.75
Deduct 20 from 20 and we're left 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:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 78227.75
If we subtract 0 from 0, 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.

Let's proceed to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 78227.75
Subtract 0 from 0 to 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.

Our division results in 78227.75 with a remaining 0.0.
