Let's divide 129518 by 1
We're looking to find how many times 1 goes into 129518.

Let's proceed to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 1 from 1, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Step 2:
1 goes into 2 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 2 from 2, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Moving on to step 3:
When dividing 9 by 1, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Let's proceed to step 4:
1 goes into 5 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1295.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 5:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 12951.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 129518.0
Deduct 8 from 8 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 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 129518.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 129518.0
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.

In conclusion, the division gives 129518.0 with a balance of 0.0.
