89689 ÷ 66 
We want to divide 89689 by 66.

Let's proceed to step 1:
8 divided by 66 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 66

Moving on to step 2:
66 can be fit into 89 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 66 from 89 leaves us with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 66

On to step 3:
If we divide 236 by 66, we get 3 and a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 198 from 236, we get 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 66

Let's proceed to step 4:
When dividing 388 by 66, we get 5 with a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 330 from 388 to get 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 66

Advancing to step 5:
66 can be fit into 589 8 times, resulting in a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 1358.0
If we subtract 528 from 589, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 6:
66 can be fit into 610 9 times, resulting in a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 1358.9
If we take 594 away from 610, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
66 can be fit into 160 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1358.92
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
66 goes into 280 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1358.924
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
If we divide 160 by 66, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1358.9242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
66 can be fit into 280 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 1358.92424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
66 goes into 160 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1358.924242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
280 divided by 66 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1358.9242424
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
66 goes into 160 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1358.92424242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 1358.92424242 with a remaining 2.8e-08.
