Let's divide 386225 by 15
We're looking to find how many times 15 goes into 386225.

On to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 15

Step 2:
The number 15 fits into 38 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 38, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

Advancing to step 3:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 11 after subtracting 75 from 86.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 15

Let's proceed to step 4:
15 can be fit into 112 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtracting 105 from 112 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

Going ahead to step 5:
When dividing 72 by 15, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2574.0
Subtract 60 from 72 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 15

On to step 6:
15 goes into 125 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 25748.0
If we take 120 away from 125, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 25748.3
If we subtract 45 from 50, 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.

Let's proceed to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 25748.33
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 25748.33 with a remainder of 0.005.
