912800 ÷ 15 
We want to figure out the number of times 912800 can be divided by 15.

Going ahead to step 1:
15 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 15

Moving on to step 2:
91 divided by 15 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 90 from 91, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

Advancing to step 3:
12 divided by 15 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 15

Moving on to step 4:
15 can be fit into 128 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 608.0
The remainder is 8 after subtracting 120 from 128.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Moving on to step 5:
When dividing 80 by 15, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6085.0
If we take 75 away from 80, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 15

Let's proceed to step 6:
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: 60853.0
Deduct 45 from 50 and we're left 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.

Moving on to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 60853.3
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.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 60853.33
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.

After the division, we end up with 60853.33 and a remainder of 0.005.
