129065 ÷ 75 
We want to divide 129065 by 75.

On to step 1:
75 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 75

Let's proceed to step 2:
If we divide 12 by 75, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 75

Let's proceed to step 3:
When dividing 129 by 75, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 129 and we're left with 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 75

Going ahead to step 4:
540 divided by 75 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 525 from 540 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 75

Step 5:
When dividing 156 by 75, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 172.0
Subtracting 150 from 156 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 75

Step 6:
The number 75 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 1720.0
Subtracting 0 from 65 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
If we divide 650 by 75, we get 8 and a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 1720.8
Deduct 600 from 650 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 1720.86
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 1720.866
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 1720.866 with a remainder of 0.005.
