We're dividing 313278 by 42 
We want to divide 313278 by 42.

Let's proceed to step 1:
42 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 42

Step 2:
42 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 42

Going ahead to step 3:
42 goes into 313 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 294 from 313 leaves us with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 42

On to step 4:
When dividing 192 by 42, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 168 from 192 and we're left with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 42

Going ahead to step 5:
247 divided by 42 is 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 745.0
Subtract 210 from 247 to get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 42

Going ahead to step 6:
42 goes into 378 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 7459.0
Deduct 378 from 378 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.

Going ahead to step 7:
0 divided by 42 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7459.0
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.

Moving on to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7459.0
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 outcome is 7459.0, with a leftover of 0.0.
