88139 ÷ 80 
Let's see how many times 80 fits into 88139.

Let's proceed to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 80

Let's proceed to step 2:
When dividing 88 by 80, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 8 after subtracting 80 from 88.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 80

Going ahead to step 3:
The number 80 fits into 81 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 80 from 81, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 80

Step 4:
The number 80 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtract 0 from 13 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 80

Let's proceed to step 5:
If we divide 139 by 80, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1101.0
Subtracting 80 from 139 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 6:
When dividing 590 by 80, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 1101.7
Subtracting 560 from 590 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 1101.73
Deduct 240 from 300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1101.737
Subtract 560 from 600 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 9:
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: 1101.7375
Subtract 400 from 400 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.

Moving on to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1101.7375
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.

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: 1101.7375
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.

Our division results in 1101.7375 with a remaining 0.0.
