We're dividing 308790 by 25 
We want to divide 308790 by 25.

Let's proceed to step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 25

Moving on to step 2:
25 goes into 30 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 25 from 30 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 25

On to step 3:
58 divided by 25 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 8 after subtracting 50 from 58.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 25

Step 4:
If we divide 87 by 25, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtracting 75 from 87 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 25

Step 5:
25 can be fit into 129 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 1235.0
Subtracting 125 from 129 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 25

On to step 6:
When dividing 40 by 25, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 12351.0
If we take 25 away from 40, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
25 goes into 150 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 12351.6
The remainder is 0 after subtracting 150 from 150.
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 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12351.6
If we subtract 0 from 0, 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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12351.6
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.

The final outcome is 12351.6, with a leftover of 0.0.
