We're dividing 423030 by 4 
We want to figure out the number of times 423030 can be divided by 4.

Let's proceed to step 1:
4 goes into 4 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 4

Step 2:
The number 4 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 4

On to step 3:
4 can be fit into 23 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 20 from 23 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 4

Advancing to step 4:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 1057.0
If we take 28 away from 30, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Going ahead to step 5:
23 divided by 4 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 10575.0
If we subtract 20 from 23, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Going ahead to step 6:
4 goes into 30 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 105757.0
If we take 28 away from 30, we end up 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.

Step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 105757.5
If we subtract 20 from 20, 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.

Moving on to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 105757.5
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.

On to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 105757.5
Subtracting 0 from 0 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.

In conclusion, the division gives 105757.5 with a balance of 0.0.
