We divide 23515 by 30
We want to figure out the number of times 23515 can be divided by 30.

Going ahead to step 1:
30 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 30

Advancing to step 2:
If we divide 23 by 30, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 30

Going ahead to step 3:
When dividing 235 by 30, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 25 after subtracting 210 from 235.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 30

Let's proceed to step 4:
30 can be fit into 251 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we subtract 240 from 251, we get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 30

Advancing to step 5:
When dividing 115 by 30, we get 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 783.0
If we subtract 90 from 115, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 6:
The number 30 fits into 250 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 783.8
Deduct 240 from 250 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 783.83
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 30 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 783.833
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 783.833 and a remainder of 0.001.
