We look at the division of 305415 by 4 
We want to figure out the number of times 305415 can be divided by 4.

Going ahead to step 1:
4 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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

On to step 2:
4 goes into 30 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 28 from 30, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

Step 3:
4 can be fit into 25 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 24 from 25 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Let's proceed to step 4:
If we divide 14 by 4, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 763.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

Advancing to step 5:
When dividing 21 by 4, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 7635.0
If we take 20 away from 21, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

On to step 6:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 76353.0
The remainder is 3 after subtracting 12 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 76353.7
Subtracting 28 from 30 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.

On to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 76353.75
Subtracting 20 from 20 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.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 76353.75
If we subtract 0 from 0, we 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.

Let's proceed to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 76353.75
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.

Our division results in 76353.75 with a remaining 0.0.
