We're dividing 172264 by 1 
We want to figure out the number of times 172264 can be divided by 1.

Let's proceed to step 1:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 2:
If we divide 7 by 1, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 7 from 7 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Going ahead to step 3:
When dividing 2 by 1, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 172.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Moving on to step 4:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1722.0
If we take 2 away from 2, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 5:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 17226.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

On to step 6:
4 divided by 1 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 172264.0
If we subtract 4 from 4, 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 172264.0
Subtracting 0 from 0 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.

Going ahead to step 8:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 172264.0
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 172264.0, with a leftover of 0.0.
