We look at the division of 303589 by 4 
We want to figure out the number of times 303589 can be divided by 4.

Advancing to step 1:
When dividing 3 by 4, we get 0 with 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 / 4

Step 2:
4 goes into 30 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 28 from 30 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 4

Let's proceed to step 3:
23 divided by 4 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 3 after subtracting 20 from 23.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 4

Advancing to step 4:
4 goes into 35 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 758.0
The remainder is 3 after subtracting 32 from 35.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Moving on to step 5:
If we divide 38 by 4, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 7589.0
If we take 36 away from 38, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

Going ahead to step 6:
If we divide 29 by 4, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 75897.0
Deduct 28 from 29 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 75897.2
The remainder is 2 after subtracting 8 from 10.
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 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 75897.25
Deduct 20 from 20 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.

On to step 9:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 75897.25
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.

Step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 75897.25
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 final result is 75897.25 with a remainder of 0.0.
