879754 ÷ 15 
We want to divide 879754 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
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 15

Moving on to step 2:
87 divided by 15 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 75 away from 87, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 15

Let's proceed to step 3:
The number 15 fits into 129 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we take 120 away from 129, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 15

Let's proceed to step 4:
97 divided by 15 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 586.0
If we take 90 away from 97, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 15

Going ahead to step 5:
When dividing 75 by 15, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5865.0
If we take 75 away from 75, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

Going ahead to step 6:
4 divided by 15 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 58650.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 15, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 58650.2
If we take 30 away from 40, we end up 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.

Let's proceed to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 58650.26
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.

Step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 58650.266
Deduct 90 from 100 and we're left 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 result is 58650.266 with a remainder of 0.001.
