We're dividing 936403 by 25 
We want to divide 936403 by 25.

Step 1:
25 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 25

On to step 2:
If we divide 93 by 25, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 75 away from 93, we end up with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 25

Advancing to step 3:
25 can be fit into 186 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 175 from 186 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 25

On to step 4:
The number 25 fits into 114 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 374.0
Subtract 100 from 114 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 25

On to step 5:
If we divide 140 by 25, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 3745.0
Deduct 125 from 140 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 25

Let's proceed to step 6:
If we divide 153 by 25, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 37456.0
Subtract 150 from 153 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
25 goes into 30 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 37456.1
Subtract 25 from 30 to 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.

Moving on to step 8:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 37456.12
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.

Moving on to 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: 37456.12
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.

On to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37456.12
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.

After the division, we end up with 37456.12 and a remainder of 0.0.
