2511 divided by 30 
We want to divide 2511 by 30.

Going ahead to step 1:
30 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 30

Moving on to step 2:
The number 30 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 30

On to step 3:
When dividing 251 by 30, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 11 after subtracting 240 from 251.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 30

Going ahead to step 4:
The number 30 fits into 111 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 90 from 111 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 5:
30 can be fit into 210 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 83.7
If we subtract 210 from 210, 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.

Moving on to step 6:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 83.7
Subtracting 0 from 0 leaves us with 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 7:
If we divide 0 by 30, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83.7
Subtracting 0 from 0 leaves us with 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 quotient of the division is 83.7, and the remainder is 0.0.
