We divide 172788 by 17
We want to figure out the number of times 172788 can be divided by 17.

Step 1:
The number 17 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 17

Advancing to step 2:
When dividing 17 by 17, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 17 from 17, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 17

Advancing to step 3:
When dividing 2 by 17, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 17

Going ahead to step 4:
27 divided by 17 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
The remainder is 10 after subtracting 17 from 27.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 17

Let's proceed to step 5:
17 can be fit into 108 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 1016.0
The remainder is 6 after subtracting 102 from 108.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 17

Going ahead to step 6:
17 goes into 68 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 10164.0
Subtracting 68 from 68 leaves us 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.

Moving on to step 7:
17 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10164.0
Subtract 0 from 0 to 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.

On to step 8:
0 divided by 17 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10164.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10164.0, with a leftover of 0.0.
