We look at the division of 804386 by 15 
We're looking to find how many times 15 goes into 804386.

On to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

Moving on to step 2:
If we divide 80 by 15, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 75 away from 80, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Moving on to step 3:
54 divided by 15 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 9 after subtracting 45 from 54.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 15

Going ahead to step 4:
93 divided by 15 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 536.0
Subtract 90 from 93 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 15

On to step 5:
If we divide 38 by 15, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5362.0
Subtract 30 from 38 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

Step 6:
When dividing 86 by 15, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 53625.0
Deduct 75 from 86 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 53625.7
If we take 105 away from 110, 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:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 53625.73
If we take 45 away from 50, 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.

Let's proceed to step 9:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 53625.733
Subtract 45 from 50 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.

The quotient of the division is 53625.733, and the remainder is 0.0005.
