921150 ÷ 15 
We want to figure out the number of times 921150 can be divided by 15.

Step 1:
If we divide 9 by 15, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 15

Let's proceed to step 2:
When dividing 92 by 15, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 90 from 92 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 15

On to step 3:
15 can be fit into 21 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 15 from 21, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 15

Going ahead to step 4:
The number 15 fits into 61 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 614.0
Subtract 60 from 61 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 15

Going ahead to step 5:
15 divided by 15 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 6141.0
Deduct 15 from 15 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 15

On to step 6:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 61410.0
Deduct 0 from 0 and we're left 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.

On to step 7:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 61410.0
Subtracting 0 from 0 leaves us 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:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61410.0
If we take 0 away from 0, 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.

The quotient of the division is 61410.0, and the remainder is 0.0.
