511286 divided by 30 
We're looking to find how many times 30 goes into 511286.

Let's proceed to step 1:
5 divided by 30 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 30

Advancing to step 2:
51 divided by 30 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 21 after subtracting 30 from 51.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 30

Moving on to step 3:
30 goes into 211 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 210 from 211 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 30

Going ahead to step 4:
The number 30 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 30

Let's proceed to step 5:
If we divide 128 by 30, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1704.0
If we subtract 120 from 128, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 30

Advancing to step 6:
If we divide 86 by 30, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 17042.0
Subtract 60 from 86 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
260 divided by 30 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 17042.8
Deduct 240 from 260 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 30 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 17042.86
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 17042.866
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 17042.866, with a leftover of 0.002.
