We're dividing 86666 by 89 
Our goal is to divide 86666 by 89.

Advancing to step 1:
The number 89 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 89

Going ahead to step 2:
If we divide 86 by 89, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 89

Going ahead to step 3:
When dividing 866 by 89, we get 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 801 from 866 leaves us with 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 89

Step 4:
The number 89 fits into 656 7 times, leaving a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 623 from 656 to get 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 89

Going ahead to step 5:
336 divided by 89 is 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 973.0
Deduct 267 from 336 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 6:
The number 89 fits into 690 7 times, leaving a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 973.7
If we subtract 623 from 690, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
670 divided by 89 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 973.77
If we take 623 away from 670, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 973.77, and the remainder is 0.047.
