We look at the division of 305010 by 4 
Let's see how many times 4 fits into 305010.

On to step 1:
4 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

Step 2:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 28 from 30 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 4

Step 3:
25 divided by 4 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

On to step 4:
If we divide 10 by 4, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 762.0
Deduct 8 from 10 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 4

On to step 5:
If we divide 21 by 4, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 7625.0
If we take 20 away from 21, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

Let's proceed to step 6:
When dividing 10 by 4, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 76252.0
Subtracting 8 from 10 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 76252.5
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 76252.5
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.

Advancing to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 76252.5
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.

The quotient of the division is 76252.5, and the remainder is 0.0.
