77590064 divided by 5 
Our goal is to divide 77590064 by 5.

Going ahead to step 1:
5 can be fit into 7 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 5 from 7.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 5

Let's proceed to step 2:
When dividing 27 by 5, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 25 from 27 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 5

Going ahead to step 3:
When dividing 25 by 5, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 155.0
If we subtract 25 from 25, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 5

Moving on to step 4:
5 goes into 9 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1551.0
The remainder is 4 after subtracting 5 from 9.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 5

Let's proceed to step 5:
The number 5 fits into 40 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 15518.0
If we take 40 away from 40, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 5

Going ahead to step 6:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 155180.0
If we subtract 0 from 0, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 5

Moving on to step 7:
6 divided by 5 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1551801.0
Deduct 5 from 6 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 5

Step 8:
The number 5 fits into 14 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 15518012.0
The remainder is 4 after subtracting 10 from 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 5 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 15518012.8
If we subtract 40 from 40, 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.

Step 10:
5 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15518012.8
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.

Going ahead to step 11:
5 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15518012.8
Subtract 0 from 0 to 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.

The final outcome is 15518012.8, with a leftover of 0.0.
