We're dividing 315094 by 25 
Our goal is to divide 315094 by 25.

Going ahead to step 1:
The number 25 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 25

Going ahead to step 2:
The number 25 fits into 31 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 25 from 31 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 25

Step 3:
25 can be fit into 65 2 times, resulting in a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 50 from 65 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 25

Let's proceed to step 4:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we subtract 150 from 150, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 25

Moving on to step 5:
25 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 1260.0
Subtract 0 from 9 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 25

Moving on to step 6:
When dividing 94 by 25, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 12603.0
The remainder is 19 after subtracting 75 from 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 25, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 12603.7
If we take 175 away from 190, 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.

Advancing to step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 12603.76
If we take 150 away from 150, we end up 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.

Let's proceed to step 9:
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: 12603.76
If we take 0 away from 0, we end up 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.

Let's proceed to step 10:
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: 12603.76
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.

After the division, we end up with 12603.76 and a remainder of 0.0.
