We're dividing 306445 by 25 
Our goal is to divide 306445 by 25.

Step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 25

Moving on to step 2:
If we divide 30 by 25, we get 1 and 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.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 25

Advancing to step 3:
When dividing 56 by 25, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 6 after subtracting 50 from 56.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 25

Step 4:
64 divided by 25 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we take 50 away from 64, we end up with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 25

On to step 5:
25 goes into 144 5 times with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 1225.0
If we subtract 125 from 144, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 25

Let's proceed to step 6:
The number 25 fits into 195 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 12257.0
The remainder is 20 after subtracting 175 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
The number 25 fits into 200 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 12257.8
If we subtract 200 from 200, 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.

Let's proceed to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12257.8
Subtract 0 from 0 to 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 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12257.8
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 12257.8, with a leftover of 0.0.
