We look at the division of 393901 by 25 
We want to divide 393901 by 25.

Step 1:
3 divided by 25 is 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 25

Going ahead to step 2:
The number 25 fits into 39 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 25 away from 39, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 25

Step 3:
25 can be fit into 143 5 times, resulting in a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 125 from 143 and we're left with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 25

Moving on to step 4:
If we divide 189 by 25, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 157.0
If we subtract 175 from 189, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 25

Step 5:
25 goes into 140 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1575.0
If we take 125 away from 140, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 25

Going ahead to step 6:
When dividing 151 by 25, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 15756.0
Subtracting 150 from 151 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 25 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15756.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 15756.04
If we take 100 away from 100, 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 9:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15756.04
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.

Advancing to step 10:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15756.04
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.

Our division results in 15756.04 with a remaining 0.0.
