We look at the division of 87664116 by 80 
We're looking to find how many times 80 goes into 87664116.

Moving on to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 80

Advancing to step 2:
87 divided by 80 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 7 after subtracting 80 from 87.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 80

Let's proceed to step 3:
80 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 76 to get 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 80

Step 4:
766 divided by 80 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 46 after subtracting 720 from 766.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 80

Moving on to step 5:
464 divided by 80 is 5 with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
Deduct 400 from 464 and we're left with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 80

Moving on to step 6:
80 can be fit into 641 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 10958.0
Subtract 640 from 641 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 80

Let's proceed to step 7:
The number 80 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 109580.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 80

Let's proceed to step 8:
116 divided by 80 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1095801.0
If we take 80 away from 116, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 80 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1095801.4
Deduct 320 from 360 and we're left with 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 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1095801.45
Subtracting 400 from 400 leaves us 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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1095801.45
Subtracting 0 from 0 leaves us 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 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1095801.45
Subtracting 0 from 0 leaves us 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.

The final result is 1095801.45 with a remainder of 0.0.
