172616 ÷ 2 
We're looking to find how many times 2 goes into 172616.

On to step 1:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Going ahead to step 2:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 1 after subtracting 16 from 17.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Going ahead to step 3:
2 can be fit into 12 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 0 after subtracting 12 from 12.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Let's proceed to step 4:
2 goes into 6 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Going ahead to step 5:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 8630.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Step 6:
2 goes into 16 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 86308.0
Deduct 16 from 16 and we're left 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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 86308.0
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 86308.0
If we subtract 0 from 0, we 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.

Our division results in 86308.0 with a remaining 0.0.
