We look at the division of 76309404 by 868 
We want to divide 76309404 by 868.

Moving on to step 1:
If we divide 7 by 868, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 868

Let's proceed to step 2:
The number 868 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 868

On to step 3:
868 goes into 763 0 times with a remainder of 763.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 763, we get 763.
Include the next digit (0) from the dividend after 763, then repeat: 7630 / 868

Step 4:
When dividing 7630 by 868, we get 8 with a remainder of 686.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 6944 away from 7630, we end up with 686.
Bring next digit (9) of the dividend behind the 686 and repeat the process: 6869 / 868

Going ahead to step 5:
If we divide 6869 by 868, we get 7 and a remainder of 793.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 6076 away from 6869, we end up with 793.
Take the next digit (4) from the dividend and append it to 793, then repeat: 7934 / 868

Step 6:
The number 868 fits into 7934 9 times, leaving a remainder of 122.
The next digit of our result is 9. 
Result so far: 879.0
Deduct 7812 from 7934 and we're left with 122.
Fetch the next digit (0) from the dividend, attach it to 122 and continue: 1220 / 868

Moving on to step 7:
868 goes into 1220 1 times with a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 8791.0
Subtract 868 from 1220 to get 352.
Fetch the next digit (4) from the dividend, attach it to 352 and continue: 3524 / 868

Step 8:
868 goes into 3524 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 87914.0
If we subtract 3472 from 3524, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
When dividing 520 by 868, we get 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 87914.0
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 10:
The number 868 fits into 5200 5 times, leaving a remainder of 860.
The number 5 becomes the next digit in our result. 
Result so far: 87914.05
If we subtract 4340 from 5200, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 11:
When dividing 8600 by 868, we get 9 with a remainder of 788.
Use 9 as the next digit of our solution. 
Result so far: 87914.059
Subtracting 7812 from 8600 leaves us with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 12:
868 goes into 7880 9 times with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 87914.0599
Deduct 7812 from 7880 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 87914.0599 with a remainder of 0.00068.
