Let's divide 861528 by 30
We want to divide 861528 by 30.

On to step 1:
If we divide 8 by 30, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 30

Let's proceed to step 2:
30 goes into 86 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 60 from 86, we get 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 30

Advancing to step 3:
The number 30 fits into 261 8 times, leaving a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 240 from 261 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 30

Let's proceed to step 4:
30 can be fit into 215 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 287.0
If we subtract 210 from 215, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 30

Advancing to step 5:
52 divided by 30 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2871.0
If we take 30 away from 52, we end up with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 30

Going ahead to step 6:
30 goes into 228 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 28717.0
Deduct 210 from 228 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 30, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 28717.6
If we take 180 away from 180, we end up 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.

Step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 28717.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28717.6
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 final outcome is 28717.6, with a leftover of 0.0.
