We're dividing 678805 by 15 
We want to figure out the number of times 678805 can be divided by 15.

Advancing to step 1:
15 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 15

Let's proceed to step 2:
The number 15 fits into 67 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 7 after subtracting 60 from 67.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Advancing to step 3:
15 can be fit into 78 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 3 after subtracting 75 from 78.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

On to step 4:
When dividing 38 by 15, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 452.0
Subtracting 30 from 38 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

Moving on to step 5:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4525.0
Deduct 75 from 80 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 15

On to step 6:
15 can be fit into 55 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 45253.0
If we subtract 45 from 55, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 45253.6
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 45253.66
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 45253.66, with a leftover of 0.01.
