We look at the division of 305403 by 5 
We want to divide 305403 by 5.

Step 1:
3 divided by 5 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 5

Going ahead to step 2:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 0 after subtracting 30 from 30.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 5

Going ahead to step 3:
5 divided by 5 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtracting 5 from 5 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 5

Going ahead to step 4:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 610.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 5

Step 5:
40 divided by 5 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 6108.0
The remainder is 0 after subtracting 40 from 40.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 5

Step 6:
5 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 61080.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
5 goes into 30 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 61080.6
Subtracting 30 from 30 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 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 61080.6
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.

Step 9:
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: 61080.6
Subtract 0 from 0 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.

Our division results in 61080.6 with a remaining 0.0.
