We look at the division of 873260 by 15 
We want to divide 873260 by 15.

Going ahead to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 15

Step 2:
87 divided by 15 is 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 12 after subtracting 75 from 87.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 15

Step 3:
When dividing 123 by 15, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtract 120 from 123 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 15

On to step 4:
32 divided by 15 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 582.0
If we take 30 away from 32, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 15

Moving on to step 5:
26 divided by 15 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 5821.0
If we take 15 away from 26, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 15

Step 6:
When dividing 110 by 15, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 58217.0
Deduct 105 from 110 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 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 58217.3
If we take 45 away from 50, we end up 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.

Going ahead to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 58217.33
Subtract 45 from 50 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.

After the division, we end up with 58217.33 and a remainder of 0.005.
