15178877 ÷ 17 
We want to figure out the number of times 15178877 can be divided by 17.

Advancing to step 1:
17 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 17

Going ahead to step 2:
When dividing 15 by 17, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 17

Going ahead to step 3:
When dividing 151 by 17, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 136 from 151 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 17

Going ahead to step 4:
The number 17 fits into 157 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 89.0
Subtracting 153 from 157 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 17

On to step 5:
The number 17 fits into 48 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 892.0
Subtracting 34 from 48 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 17

Moving on to step 6:
17 goes into 148 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 8928.0
The remainder is 12 after subtracting 136 from 148.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 17

Let's proceed to step 7:
When dividing 127 by 17, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 89287.0
If we take 119 away from 127, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 17

Step 8:
87 divided by 17 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 892875.0
Subtracting 85 from 87 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 892875.1
Subtract 17 from 20 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 892875.11
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 892875.11, with a leftover of 0.013.
