921264 ÷ 15 
We're looking to find how many times 15 goes into 921264.

On to step 1:
15 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 15

Let's proceed to step 2:
15 can be fit into 92 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 90 from 92 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 15

Step 3:
15 goes into 21 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 15 from 21 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 15

On to step 4:
The number 15 fits into 62 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 614.0
If we subtract 60 from 62, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 15

Advancing to step 5:
When dividing 26 by 15, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 6141.0
Deduct 15 from 26 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 15

Moving on to step 6:
15 goes into 114 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 61417.0
The remainder is 9 after subtracting 105 from 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 15 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 61417.6
If we take 90 away from 90, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 61417.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 61417.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 61417.6 with a remainder of 0.0.
