We're dividing 425943 by 30 
We want to figure out the number of times 425943 can be divided by 30.

Step 1:
4 divided by 30 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 30

Going ahead to step 2:
30 goes into 42 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 30 from 42, we get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 30

Step 3:
30 can be fit into 125 4 times, resulting in a remainder of 5.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 5 after subtracting 120 from 125.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 30

Step 4:
When dividing 59 by 30, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 141.0
Subtract 30 from 59 to get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 30

Let's proceed to step 5:
294 divided by 30 is 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 1419.0
The remainder is 24 after subtracting 270 from 294.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 30

On to step 6:
30 goes into 243 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 14198.0
Subtracting 240 from 243 leaves us with 3.
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:
When dividing 30 by 30, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 14198.1
Deduct 30 from 30 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.

Let's proceed to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14198.1
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.

Let's proceed to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14198.1
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.

After the division, we end up with 14198.1 and a remainder of 0.0.
