172726 ÷ 4 
Let's see how many times 4 fits into 172726.

Step 1:
1 divided by 4 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 4

Going ahead to step 2:
The number 4 fits into 17 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 16 away from 17, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 4

Step 3:
4 can be fit into 12 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 12 from 12 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 4

Let's proceed to step 4:
The number 4 fits into 7 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 431.0
The remainder is 3 after subtracting 4 from 7.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

On to step 5:
The number 4 fits into 32 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 4318.0
Subtract 32 from 32 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 4

Let's proceed to step 6:
When dividing 6 by 4, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 43181.0
Subtracting 4 from 6 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.

Step 7:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 43181.5
If we subtract 20 from 20, 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.

Moving on to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43181.5
Deduct 0 from 0 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.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43181.5
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.

After the division, we end up with 43181.5 and a remainder of 0.0.
