We're dividing 71306448 by 866 
Let's see how many times 866 fits into 71306448.

Going ahead to step 1:
7 divided by 866 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 866

On to step 2:
866 goes into 71 0 times with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 866

Advancing to step 3:
866 can be fit into 713 0 times, resulting in a remainder of 713.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 713, we end up with 713.
Grab the next digit (0) from the dividend, add it to 713, then carry on: 7130 / 866

On to step 4:
866 goes into 7130 8 times with a remainder of 202.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6928 from 7130 to get 202.
Fetch the next digit (6) from the dividend, attach it to 202 and continue: 2026 / 866

On to step 5:
2026 divided by 866 is 2 with a remainder of 294.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtracting 1732 from 2026 leaves us with 294.
Include the next digit (4) from the dividend after 294, then repeat: 2944 / 866

Moving on to step 6:
866 goes into 2944 3 times with a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 823.0
The remainder is 346 after subtracting 2598 from 2944.
Append the next digit (4) from the dividend to 346 and continue with: 3464 / 866

Going ahead to step 7:
If we divide 3464 by 866, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 8234.0
Subtract 3464 from 3464 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 866

Step 8:
866 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 82340.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 866 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 82340.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
866 goes into 800 0 times with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 82340.0
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 82340.0, and the remainder is 0.8.
