678893 divided by 15 
We want to figure out the number of times 678893 can be divided by 15.

Step 1:
When dividing 6 by 15, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 15

Moving on to step 2:
When dividing 67 by 15, we get 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 60 from 67 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 15

On to step 3:
78 divided by 15 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 75 from 78 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 15

Advancing to step 4:
If we divide 38 by 15, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 452.0
The remainder is 8 after subtracting 30 from 38.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 15

Let's proceed to step 5:
When dividing 89 by 15, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 4525.0
Subtract 75 from 89 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 15

Let's proceed to step 6:
15 can be fit into 143 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 45259.0
If we subtract 135 from 143, we get 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:
80 divided by 15 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 45259.5
Subtract 75 from 80 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.

Let's proceed to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 45259.53
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.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 45259.533
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.

The final outcome is 45259.533, with a leftover of 0.0005.
