We look at the division of 873261 by 15 
We want to figure out the number of times 873261 can be divided by 15.

Moving on to step 1:
15 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 15

Moving on to step 2:
87 divided by 15 is 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 75 from 87 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 15

Step 3:
The number 15 fits into 123 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
The remainder is 3 after subtracting 120 from 123.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 15

Moving on to step 4:
The number 15 fits into 32 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 582.0
Deduct 30 from 32 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 15

Let's proceed to step 5:
15 goes into 26 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 5821.0
Subtracting 15 from 26 leaves us with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 15

Step 6:
111 divided by 15 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 58217.0
Subtract 105 from 111 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
60 divided by 15 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 58217.4
If we take 60 away from 60, 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.

On to step 8:
0 divided by 15 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 58217.4
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.

On to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 58217.4
If we subtract 0 from 0, we 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.

Our division results in 58217.4 with a remaining 0.0.
