88102870 divided by 80 
Let's see how many times 80 fits into 88102870.

On to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 80

Moving on to step 2:
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: 1.0
Subtract 80 from 88 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 80

Advancing to step 3:
80 can be fit into 81 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 1 after subtracting 80 from 81.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 80

Moving on to step 4:
When dividing 10 by 80, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 10, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 80

Step 5:
102 divided by 80 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1101.0
Deduct 80 from 102 and we're left with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 80

Step 6:
When dividing 228 by 80, we get 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 11012.0
Subtract 160 from 228 to get 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 80

Moving on to step 7:
80 can be fit into 687 8 times, resulting in a remainder of 47.
The next digit of our result is 8. 
Result so far: 110128.0
If we take 640 away from 687, we end up with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 80

Moving on to step 8:
80 goes into 470 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 1101285.0
Subtract 400 from 470 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 1101285.8
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1101285.87
The remainder is 40 after subtracting 560 from 600.
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 11:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1101285.875
The remainder is 0 after subtracting 400 from 400.
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:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1101285.875
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.

Moving on to step 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1101285.875
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.

The quotient of the division is 1101285.875, and the remainder is 0.0.
