We're dividing 786430 by 25 
Our goal is to divide 786430 by 25.

On to step 1:
25 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 25

Let's proceed to step 2:
78 divided by 25 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 75 from 78 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 25

Going ahead to step 3:
The number 25 fits into 36 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 25 from 36 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 25

Step 4:
25 can be fit into 114 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Deduct 100 from 114 and we're left with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 25

Moving on to step 5:
25 can be fit into 143 5 times, resulting in a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 3145.0
Subtracting 125 from 143 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 25

On to step 6:
When dividing 180 by 25, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 31457.0
If we subtract 175 from 180, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 25 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 31457.2
The remainder is 0 after subtracting 50 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31457.2
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:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31457.2
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.

The final result is 31457.2 with a remainder of 0.0.
