We look at the division of 76788291 by 5 
We want to figure out the number of times 76788291 can be divided by 5.

On to step 1:
5 can be fit into 7 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 5 from 7, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 5

Step 2:
When dividing 26 by 5, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 25 from 26 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 5

Let's proceed to step 3:
The number 5 fits into 17 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 153.0
Subtracting 15 from 17 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 5

Let's proceed to step 4:
If we divide 28 by 5, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 1535.0
Deduct 25 from 28 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 5

Going ahead to step 5:
If we divide 38 by 5, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 15357.0
The remainder is 3 after subtracting 35 from 38.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 5

Going ahead to step 6:
5 can be fit into 32 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 153576.0
If we subtract 30 from 32, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 5

On to step 7:
29 divided by 5 is 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 1535765.0
If we subtract 25 from 29, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 5

Moving on to step 8:
If we divide 41 by 5, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 15357658.0
Deduct 40 from 41 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 5 fits into 10 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 15357658.2
If we subtract 10 from 10, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15357658.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 5, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15357658.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15357658.2 with a remainder of 0.0.
