We look at the division of 312144 by 5 
We're looking to find how many times 5 goes into 312144.

Advancing to step 1:
3 divided by 5 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 5

Moving on to step 2:
31 divided by 5 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 30 away from 31, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 5

Moving on to step 3:
12 divided by 5 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 10 from 12 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 5

On to step 4:
5 can be fit into 21 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 624.0
If we subtract 20 from 21, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 5

Going ahead to step 5:
14 divided by 5 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6242.0
Subtracting 10 from 14 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 5

Step 6:
When dividing 44 by 5, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 62428.0
Subtract 40 from 44 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.

Step 7:
40 divided by 5 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 62428.8
Subtract 40 from 40 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.

Going ahead to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 62428.8
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 9:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62428.8
If we take 0 away from 0, we end up 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 62428.8, with a leftover of 0.0.
