We're dividing 517394 by 30 
We're looking to find how many times 30 goes into 517394.

Advancing to step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 30

Advancing to step 2:
If we divide 51 by 30, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 51 and we're left with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 30

Let's proceed to step 3:
When dividing 217 by 30, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 210 away from 217, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 30

Moving on to step 4:
30 can be fit into 73 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 172.0
The remainder is 13 after subtracting 60 from 73.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 30

On to step 5:
If we divide 139 by 30, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 1724.0
Deduct 120 from 139 and we're left with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 30

Going ahead to step 6:
194 divided by 30 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 17246.0
Deduct 180 from 194 and we're left 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:
When dividing 140 by 30, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 17246.4
If we take 120 away from 140, 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.

On to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 17246.46
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.

Let's proceed to step 9:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 17246.466
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.

After the division, we end up with 17246.466 and a remainder of 0.002.
