78791 ÷ 30 
We're looking to find how many times 30 goes into 78791.

Going ahead to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 30

Going ahead to step 2:
The number 30 fits into 78 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 60 from 78 leaves us with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 30

Step 3:
187 divided by 30 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 180 from 187 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 30

Let's proceed to step 4:
When dividing 79 by 30, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 262.0
If we subtract 60 from 79, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 30

Moving on to step 5:
30 can be fit into 191 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 2626.0
Subtracting 180 from 191 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 6:
When dividing 110 by 30, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 2626.3
Subtract 90 from 110 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 2626.36
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 2626.366
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 2626.366 and a remainder of 0.002.
