313886 ÷ 8 
Let's see how many times 8 fits into 313886.

Step 1:
3 divided by 8 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 8

Advancing to step 2:
The number 8 fits into 31 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 24 from 31, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 8

Let's proceed to step 3:
73 divided by 8 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 72 from 73, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 8

Moving on to step 4:
When dividing 18 by 8, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 392.0
If we subtract 16 from 18, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 8

Let's proceed to step 5:
The number 8 fits into 28 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3923.0
Subtract 24 from 28 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 8

On to step 6:
If we divide 46 by 8, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 39235.0
Subtracting 40 from 46 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 8, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 39235.7
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 39235.75
Subtracting 40 from 40 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.

Let's proceed to step 9:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39235.75
Deduct 0 from 0 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.

Advancing to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 39235.75
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 outcome is 39235.75, with a leftover of 0.0.
