We divide 129485 by 89
We want to figure out the number of times 129485 can be divided by 89.

Going ahead to step 1:
The number 89 fits into 1 0 times, leaving 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 89

Moving on to step 2:
12 divided by 89 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 89

Going ahead to step 3:
89 goes into 129 1 times with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 89 from 129 and we're left with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 89

On to step 4:
404 divided by 89 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 356 from 404 and we're left with 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 89

Step 5:
89 can be fit into 488 5 times, resulting in a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Deduct 445 from 488 and we're left with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 89

On to step 6:
When dividing 435 by 89, we get 4 with a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 1454.0
If we take 356 away from 435, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
89 can be fit into 790 8 times, resulting in a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 1454.8
The remainder is 78 after subtracting 712 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
780 divided by 89 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 1454.88
If we take 712 away from 780, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 1454.88, and the remainder is 0.068.
