9866 ÷ 89 
Our goal is to divide 9866 by 89.

Going ahead to step 1:
89 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 89

Going ahead to step 2:
89 goes into 98 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 89 from 98 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 89

Going ahead to step 3:
The number 89 fits into 96 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 89 from 96 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 89

Going ahead to step 4:
89 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtract 0 from 76 to get 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 5:
760 divided by 89 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 110.8
If we take 712 away from 760, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 6:
If we divide 480 by 89, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 110.85
Subtracting 445 from 480 leaves us 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.

Advancing to step 7:
89 goes into 350 3 times with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 110.853
Subtract 267 from 350 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 8:
If we divide 830 by 89, we get 9 and a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 110.8539
Subtracting 801 from 830 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
When dividing 290 by 89, we get 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 110.85393
Subtracting 267 from 290 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
When dividing 230 by 89, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 110.853932
If we subtract 178 from 230, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
The number 89 fits into 520 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 110.8539325
If we subtract 445 from 520, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
If we divide 750 by 89, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 110.85393258
The remainder is 38 after subtracting 712 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 110.85393258, and the remainder is 3.8e-08.
