Let's divide 76400886 by 665
We're looking to find how many times 665 goes into 76400886.

Going ahead to step 1:
The number 665 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 665

Let's proceed to step 2:
If we divide 76 by 665, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 665

On to step 3:
665 can be fit into 764 1 times, resulting in a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 665 from 764 and we're left with 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 665

Let's proceed to step 4:
665 goes into 990 1 times with a remainder of 325.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 665 from 990 to get 325.
Include the next digit (0) from the dividend after 325, then repeat: 3250 / 665

Moving on to step 5:
665 goes into 3250 4 times with a remainder of 590.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 2660 from 3250 leaves us with 590.
Fetch the next digit (8) from the dividend, attach it to 590 and continue: 5908 / 665

Advancing to step 6:
665 can be fit into 5908 8 times, resulting in a remainder of 588.
Put 8 as the next digit of the answer. 
Result so far: 1148.0
Deduct 5320 from 5908 and we're left with 588.
Take the next digit (8) from the dividend and append it to 588, then repeat: 5888 / 665

On to step 7:
The number 665 fits into 5888 8 times, leaving a remainder of 568.
The next digit of our result is 8. 
Result so far: 11488.0
The remainder is 568 after subtracting 5320 from 5888.
Include the next digit (6) from the dividend after 568, then repeat: 5686 / 665

On to step 8:
665 goes into 5686 8 times with a remainder of 366.
Write down 8 as next digit of the result. 
Result so far: 114888.0
If we take 5320 away from 5686, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 9:
3660 divided by 665 is 5 with a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 114888.5
The remainder is 335 after subtracting 3325 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 10:
The number 665 fits into 3350 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 114888.55
Subtract 3325 from 3350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 114888.55 and a remainder of 0.025.
