We're dividing 603027 by 4 
Let's see how many times 4 fits into 603027.

Moving on to step 1:
If we divide 6 by 4, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Moving on to step 2:
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: 15.0
Deduct 20 from 20 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Moving on to step 3:
3 divided by 4 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 150.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 4

Step 4:
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: 1507.0
If we take 28 away from 30, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Moving on to step 5:
4 goes into 22 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 15075.0
Subtract 20 from 22 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 4

On to step 6:
When dividing 27 by 4, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 150756.0
Subtract 24 from 27 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 150756.7
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 150756.75
If we take 20 away from 20, 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 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 150756.75
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.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 150756.75
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.

The quotient of the division is 150756.75, and the remainder is 0.0.
