We look at the division of 78088813 by 80 
We're looking to find how many times 80 goes into 78088813.

Going ahead to step 1:
7 divided by 80 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 80

Advancing to step 2:
78 divided by 80 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 80

Moving on to step 3:
780 divided by 80 is 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 720 from 780 to get 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 80

On to step 4:
608 divided by 80 is 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we take 560 away from 608, we end up with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 80

Advancing to step 5:
The number 80 fits into 488 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 976.0
Deduct 480 from 488 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 80

On to step 6:
When dividing 88 by 80, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 9761.0
Deduct 80 from 88 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 80

Let's proceed to step 7:
When dividing 81 by 80, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 97611.0
Deduct 80 from 81 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 80

Let's proceed to step 8:
If we divide 13 by 80, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 976110.0
Subtracting 0 from 13 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
If we divide 130 by 80, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 976110.1
Deduct 80 from 130 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 80, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 976110.16
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 80 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 976110.162
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 976110.1625
If we take 400 away from 400, we end up 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 13:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 976110.1625
If we take 0 away from 0, we end up 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.

Let's proceed to step 14:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 976110.1625
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 outcome is 976110.1625, with a leftover of 0.0.
