We're dividing 394538 by 15 
We want to figure out the number of times 394538 can be divided by 15.

Step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 15

Advancing to step 2:
15 can be fit into 39 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 30 from 39 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 15

On to step 3:
15 can be fit into 94 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 90 from 94 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 15

Step 4:
If we divide 45 by 15, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 263.0
Subtracting 45 from 45 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 15

Advancing to step 5:
When dividing 3 by 15, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 2630.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

Moving on to step 6:
When dividing 38 by 15, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 26302.0
Subtracting 30 from 38 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 26302.5
If we take 75 away from 80, 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 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 26302.53
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.

Going ahead to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 26302.533
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 26302.533 and a remainder of 0.0005.
