We look at the division of 305214 by 86 
Let's see how many times 86 fits into 305214.

Let's proceed to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 86

Let's proceed to step 2:
If we divide 30 by 86, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 86

Going ahead to step 3:
86 can be fit into 305 3 times, resulting in a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 47 after subtracting 258 from 305.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 86

Advancing to step 4:
The number 86 fits into 472 5 times, leaving a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 430 from 472, we get 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 86

Let's proceed to step 5:
421 divided by 86 is 4 with a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 354.0
If we subtract 344 from 421, we get 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 86

Step 6:
86 can be fit into 774 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3549.0
If we take 774 away from 774, 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.

Going ahead to step 7:
When dividing 0 by 86, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3549.0
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.

Let's proceed to step 8:
If we divide 0 by 86, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3549.0
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 3549.0, with a leftover of 0.0.
