66909 ÷ 89 
We're looking to find how many times 89 goes into 66909.

Moving on to step 1:
89 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 89

On to step 2:
When dividing 66 by 89, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 89

On to step 3:
When dividing 669 by 89, we get 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 623 from 669, we get 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 89

Moving on to step 4:
460 divided by 89 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 445 from 460 to get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 89

Step 5:
The number 89 fits into 159 1 times, leaving a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 751.0
The remainder is 70 after subtracting 89 from 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 6:
If we divide 700 by 89, we get 7 and a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 751.7
If we subtract 623 from 700, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 7:
89 goes into 770 8 times with a remainder of 58.
The next digit of our result is 8. 
Result so far: 751.78
The remainder is 58 after subtracting 712 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
89 can be fit into 580 6 times, resulting in a remainder of 46.
The next digit of our result is 6. 
Result so far: 751.786
Subtract 534 from 580 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
460 divided by 89 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 751.7865
Subtract 445 from 460 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
89 can be fit into 150 1 times, resulting in a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 751.78651
Deduct 89 from 150 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
If we divide 610 by 89, we get 6 and a remainder of 76.
The next digit of our result is 6. 
Result so far: 751.786516
Deduct 534 from 610 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
760 divided by 89 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 751.7865168
The remainder is 48 after subtracting 712 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
89 goes into 480 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 751.78651685
Deduct 445 from 480 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 751.78651685 with a balance of 3.5e-08.
