We're dividing 507628 by 30 
We want to figure out the number of times 507628 can be divided by 30.

Advancing to step 1:
30 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 30

On to step 2:
50 divided by 30 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 50, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 30

Going ahead to step 3:
30 goes into 207 6 times with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 180 away from 207, we end up with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 30

Let's proceed to step 4:
30 can be fit into 276 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtracting 270 from 276 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 30

Advancing to step 5:
The number 30 fits into 62 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1692.0
Deduct 60 from 62 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 30

Going ahead to step 6:
30 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 16920.0
Subtract 0 from 28 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
30 goes into 280 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 16920.9
If we subtract 270 from 280, 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.

Going ahead to step 8:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 16920.93
Deduct 90 from 100 and we're left 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.

Let's proceed to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 16920.933
Deduct 90 from 100 and we're left 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.

In conclusion, the division gives 16920.933 with a balance of 0.001.
