We divide 431527 by 30
Let's see how many times 30 fits into 431527.

Going ahead to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 30

Moving on to step 2:
43 divided by 30 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 30 from 43 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 30

On to step 3:
If we divide 131 by 30, we get 4 and a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 120 from 131 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 30

Step 4:
30 goes into 115 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Deduct 90 from 115 and we're left with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 30

Advancing to step 5:
30 can be fit into 252 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1438.0
Subtracting 240 from 252 leaves us with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 30

Step 6:
30 goes into 127 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 14384.0
Deduct 120 from 127 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 30 fits into 70 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 14384.2
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 14384.23
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 14384.233
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 14384.233, and the remainder is 0.001.
