597311 ÷ 30 
We want to figure out the number of times 597311 can be divided by 30.

Let's proceed to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 30

Advancing to step 2:
When dividing 59 by 30, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 30 away from 59, we end up with 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 30

Step 3:
If we divide 297 by 30, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 270 from 297, we get 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 30

Let's proceed to step 4:
The number 30 fits into 273 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
The remainder is 3 after subtracting 270 from 273.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 30

Moving on to step 5:
The number 30 fits into 31 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1991.0
If we subtract 30 from 31, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 30

On to step 6:
30 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 19910.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
30 goes into 110 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 19910.3
If we take 90 away from 110, we end up 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.

Step 8:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 19910.36
If we take 180 away from 200, we end up 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.

Let's proceed 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: 19910.366
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.

The final outcome is 19910.366, with a leftover of 0.002.
