We divide 516903 by 30
We want to divide 516903 by 30.

Moving on to step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 30

Going ahead to step 2:
When dividing 51 by 30, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 30 from 51 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 30

Step 3:
When dividing 216 by 30, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 210 from 216, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 30

On to step 4:
30 goes into 69 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Deduct 60 from 69 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 30

Going ahead to step 5:
If we divide 90 by 30, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1723.0
Subtracting 90 from 90 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 30

Step 6:
When dividing 3 by 30, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 17230.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 can be fit into 30 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 17230.1
Subtract 30 from 30 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17230.1
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17230.1
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 17230.1 with a remainder of 0.0.
