We're dividing 867742 by 15 
We're looking to find how many times 15 goes into 867742.

Let's proceed to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 15

On to step 2:
When dividing 86 by 15, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 75 away from 86, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 15

Advancing to step 3:
The number 15 fits into 117 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 105 away from 117, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 15

Moving on to step 4:
If we divide 127 by 15, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 578.0
Subtracting 120 from 127 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 15

Going ahead to step 5:
The number 15 fits into 74 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 5784.0
Subtracting 60 from 74 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 15

Moving on to step 6:
142 divided by 15 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 57849.0
Subtracting 135 from 142 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 15 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 57849.4
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 57849.46
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 57849.466
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 57849.466, with a leftover of 0.001.
