We divide 89439997 by 866
Let's see how many times 866 fits into 89439997.

Advancing to step 1:
The number 866 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 866

Moving on to step 2:
If we divide 89 by 866, we get 0 and a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 866

Step 3:
866 goes into 894 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 28 after subtracting 866 from 894.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 866

Advancing to step 4:
866 can be fit into 283 0 times, resulting in a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 283 to get 283.
Append the next digit (9) from the dividend to 283 and continue with: 2839 / 866

On to step 5:
2839 divided by 866 is 3 with a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we subtract 2598 from 2839, we get 241.
Include the next digit (9) from the dividend after 241, then repeat: 2419 / 866

Let's proceed to step 6:
866 goes into 2419 2 times with a remainder of 687.
The number 2 becomes the next digit in our result. 
Result so far: 1032.0
Deduct 1732 from 2419 and we're left with 687.
Include the next digit (9) from the dividend after 687, then repeat: 6879 / 866

Going ahead to step 7:
The number 866 fits into 6879 7 times, leaving a remainder of 817.
Use 7 as the next digit of our solution. 
Result so far: 10327.0
If we take 6062 away from 6879, we end up with 817.
Grab the next digit (7) from the dividend, add it to 817, then carry on: 8177 / 866

Let's proceed to step 8:
When dividing 8177 by 866, we get 9 with a remainder of 383.
Write down 9 as next digit of the result. 
Result so far: 103279.0
The remainder is 383 after subtracting 7794 from 8177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Step 9:
866 can be fit into 3830 4 times, resulting in a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 103279.4
The remainder is 366 after subtracting 3464 from 3830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 10:
The number 866 fits into 3660 4 times, leaving a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 103279.44
The remainder is 196 after subtracting 3464 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The quotient of the division is 103279.44, and the remainder is 0.196.
