We're dividing 617594 by 30 
We want to figure out the number of times 617594 can be divided by 30.

Advancing to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 30

Step 2:
30 goes into 61 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 60 from 61 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 30

Step 3:
30 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 30

Moving on to step 4:
The number 30 fits into 175 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 205.0
The remainder is 25 after subtracting 150 from 175.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 30

Let's proceed to step 5:
30 can be fit into 259 8 times, resulting in a remainder of 19.
The next digit of our result is 8. 
Result so far: 2058.0
Deduct 240 from 259 and we're left with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 30

Let's proceed to step 6:
If we divide 194 by 30, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 20586.0
If we take 180 away from 194, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 30 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 20586.4
The remainder is 20 after subtracting 120 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 20586.46
If we subtract 180 from 200, we get 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 9:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 20586.466
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 result is 20586.466 with a remainder of 0.002.
