Let's divide 385487 by 25
We want to divide 385487 by 25.

Advancing to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 25

Going ahead to step 2:
25 can be fit into 38 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 25 from 38 leaves us with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 25

Advancing to step 3:
135 divided by 25 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 10 after subtracting 125 from 135.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 25

On to step 4:
The number 25 fits into 104 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we subtract 100 from 104, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 25

Advancing to step 5:
25 goes into 48 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1541.0
Subtract 25 from 48 to get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 25

Step 6:
237 divided by 25 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 15419.0
If we subtract 225 from 237, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
25 goes into 120 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 15419.4
The remainder is 20 after subtracting 100 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 15419.48
If we subtract 200 from 200, 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.

Step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15419.48
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.

On to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15419.48
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 15419.48 and a remainder of 0.0.
