686300 divided by 15 
We want to divide 686300 by 15.

Let's proceed to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

On to step 2:
15 can be fit into 68 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 60 from 68, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 15

Moving on to step 3:
If we divide 86 by 15, we get 5 and a remainder of 11.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 75 from 86 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 15

Step 4:
If we divide 113 by 15, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 457.0
If we subtract 105 from 113, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

Moving on to step 5:
When dividing 80 by 15, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4575.0
If we subtract 75 from 80, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 15

On to step 6:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 45753.0
Subtracting 45 from 50 leaves us 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.

Step 7:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 45753.3
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 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 45753.33
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.

After the division, we end up with 45753.33 and a remainder of 0.005.
