We're dividing 129553 by 1 
Our goal is to divide 129553 by 1.

Step 1:
If we divide 1 by 1, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 1 from 1 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Going ahead to step 2:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
If we take 2 away from 2, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Advancing to step 3:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtract 9 from 9 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Let's proceed to step 4:
If we divide 5 by 1, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1295.0
Deduct 5 from 5 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 5:
5 divided by 1 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12955.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Moving on to step 6:
If we divide 3 by 1, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 129553.0
Deduct 3 from 3 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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 129553.0
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.

Step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 129553.0
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.

The final result is 129553.0 with a remainder of 0.0.
