307259 ÷ 25 
Our goal is to divide 307259 by 25.

Going ahead to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 25

Advancing to step 2:
25 goes into 30 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 25 from 30 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 25

Let's proceed to step 3:
57 divided by 25 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 50 from 57 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 25

Advancing to step 4:
25 can be fit into 72 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 50 from 72 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 25

Let's proceed to step 5:
25 can be fit into 225 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1229.0
If we take 225 away from 225, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 25

Going ahead to step 6:
When dividing 9 by 25, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 12290.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 25 fits into 90 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 12290.3
The remainder is 15 after subtracting 75 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 12290.36
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.

Going ahead to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12290.36
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.

Moving on to step 10:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12290.36
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.

Our division results in 12290.36 with a remaining 0.0.
