431337 divided by 30 
We want to divide 431337 by 30.

On to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 30

Let's proceed to step 2:
The number 30 fits into 43 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 30 from 43.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 30

Step 3:
If we divide 131 by 30, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 120 away from 131, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 30

Moving on to step 4:
The number 30 fits into 113 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 143.0
The remainder is 23 after subtracting 90 from 113.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 30

Moving on to step 5:
When dividing 233 by 30, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 1437.0
Subtract 210 from 233 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 30

Moving on to step 6:
237 divided by 30 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 14377.0
If we take 210 away from 237, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
If we divide 270 by 30, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 14377.9
If we subtract 270 from 270, 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 8:
30 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14377.9
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.

On to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14377.9
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.

The final result is 14377.9 with a remainder of 0.0.
