Let's divide 65761378 by 866
We're looking to find how many times 866 goes into 65761378.

Step 1:
866 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 866

Moving on to step 2:
If we divide 65 by 866, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 866

Going ahead to step 3:
When dividing 657 by 866, we get 0 with a remainder of 657.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 657 to get 657.
Grab the next digit (6) from the dividend, add it to 657, then carry on: 6576 / 866

Going ahead to step 4:
If we divide 6576 by 866, we get 7 and a remainder of 514.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 6062 from 6576 leaves us with 514.
Take the next digit (1) from the dividend and append it to 514, then repeat: 5141 / 866

On to step 5:
The number 866 fits into 5141 5 times, leaving a remainder of 811.
Use 5 as the next digit of our solution. 
Result so far: 75.0
The remainder is 811 after subtracting 4330 from 5141.
Grab the next digit (3) from the dividend, add it to 811, then carry on: 8113 / 866

Going ahead to step 6:
If we divide 8113 by 866, we get 9 and a remainder of 319.
The number 9 becomes the next digit in our result. 
Result so far: 759.0
If we subtract 7794 from 8113, we get 319.
Grab the next digit (7) from the dividend, add it to 319, then carry on: 3197 / 866

On to step 7:
3197 divided by 866 is 3 with a remainder of 599.
The next digit of our result is 3. 
Result so far: 7593.0
If we take 2598 away from 3197, we end up with 599.
Fetch the next digit (8) from the dividend, attach it to 599 and continue: 5998 / 866

Let's proceed to step 8:
866 goes into 5998 6 times with a remainder of 802.
The number 6 becomes the next digit in our result. 
Result so far: 75936.0
If we subtract 5196 from 5998, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Let's proceed to step 9:
The number 866 fits into 8020 9 times, leaving a remainder of 226.
The next digit of our result is 9. 
Result so far: 75936.9
The remainder is 226 after subtracting 7794 from 8020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
866 can be fit into 2260 2 times, resulting in a remainder of 528.
The next digit of our result is 2. 
Result so far: 75936.92
If we subtract 1732 from 2260, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 11:
The number 866 fits into 5280 6 times, leaving a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 75936.926
Subtract 5196 from 5280 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
866 goes into 840 0 times with a remainder of 840.
The next digit of our result is 0. 
Result so far: 75936.926
The remainder is 840 after subtracting 0 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 13:
When dividing 8400 by 866, we get 9 with a remainder of 606.
Put 9 as the next digit of the answer. 
Result so far: 75936.92609
Deduct 7794 from 8400 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Moving on to step 14:
6060 divided by 866 is 6 with a remainder of 864.
The next digit of our result is 6. 
Result so far: 75936.926096
Subtract 5196 from 6060 to get 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Going ahead to step 15:
The number 866 fits into 8640 9 times, leaving a remainder of 846.
The number 9 becomes the next digit in our result. 
Result so far: 75936.9260969
The remainder is 846 after subtracting 7794 from 8640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Going ahead to step 16:
8460 divided by 866 is 9 with a remainder of 666.
The number 9 becomes the next digit in our result. 
Result so far: 75936.92609699
If we take 7794 away from 8460, we end up with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

The final outcome is 75936.92609699, with a leftover of 6.66e-07.
