129081 ÷ 85 
Our goal is to divide 129081 by 85.

Advancing to step 1:
If we divide 1 by 85, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 85

Moving on to step 2:
85 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 85

Advancing to step 3:
When dividing 129 by 85, we get 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 85 from 129 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 85

On to step 4:
440 divided by 85 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 425 from 440 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 85

On to step 5:
When dividing 158 by 85, we get 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we take 85 away from 158, we end up with 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 85

Advancing to step 6:
The number 85 fits into 731 8 times, leaving a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 1518.0
Subtract 680 from 731 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
510 divided by 85 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1518.6
If we subtract 510 from 510, 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.

Let's proceed to step 8:
When dividing 0 by 85, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1518.6
If we subtract 0 from 0, 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.

On to step 9:
The number 85 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1518.6
If we subtract 0 from 0, 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.

The final result is 1518.6 with a remainder of 0.0.
