505431 divided by 30 
Our goal is to divide 505431 by 30.

Moving on to step 1:
30 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 30

Let's proceed to step 2:
50 divided by 30 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 50 to get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 30

Step 3:
30 can be fit into 205 6 times, resulting in a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 180 from 205 leaves us with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 30

On to step 4:
If we divide 254 by 30, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Subtracting 240 from 254 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 30

Going ahead to step 5:
The number 30 fits into 143 4 times, leaving a remainder of 23.
The next digit of our result is 4. 
Result so far: 1684.0
Deduct 120 from 143 and we're left with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 30

Advancing to step 6:
The number 30 fits into 231 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 16847.0
Subtracting 210 from 231 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 30 fits into 210 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 16847.7
Deduct 210 from 210 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.

Step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16847.7
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.

Moving on to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16847.7
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.

After the division, we end up with 16847.7 and a remainder of 0.0.
