We look at the division of 313427 by 78 
Let's see how many times 78 fits into 313427.

Advancing to step 1:
3 divided by 78 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 78

Moving on to step 2:
78 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 78

Going ahead to step 3:
When dividing 313 by 78, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 312 from 313 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 78

Moving on to step 4:
14 divided by 78 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 78

Advancing to step 5:
78 can be fit into 142 1 times, resulting in a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 401.0
If we subtract 78 from 142, we get 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 78

Advancing to step 6:
If we divide 647 by 78, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 4018.0
If we take 624 away from 647, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
78 can be fit into 230 2 times, resulting in a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 4018.2
Subtract 156 from 230 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
740 divided by 78 is 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 4018.29
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
The number 78 fits into 380 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 4018.294
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 4018.2948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
78 goes into 560 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 4018.29487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 78 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 4018.294871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The next digit of our result is 7. 
Result so far: 4018.2948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 14:
If we divide 740 by 78, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4018.29487179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 4018.29487179, with a leftover of 3.8e-08.
