30858 divided by 30 
Our goal is to divide 30858 by 30.

On to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 30

Step 2:
When dividing 30 by 30, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 30

Moving on to step 3:
The number 30 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 30

Advancing to step 4:
If we divide 85 by 30, we get 2 and a remainder of 25.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 25 after subtracting 60 from 85.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 30

Let's proceed to step 5:
30 goes into 258 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028.0
If we subtract 240 from 258, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 6:
If we divide 180 by 30, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1028.6
If we subtract 180 from 180, 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.

On to step 7:
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: 1028.6
Deduct 0 from 0 and we're left 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.

Going ahead to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1028.6
If we take 0 away from 0, 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.

The final outcome is 1028.6, with a leftover of 0.0.
