Let's divide 90872 by 80
Our goal is to divide 90872 by 80.

Moving on to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 80

Step 2:
80 goes into 90 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 80 from 90 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 80

Step 3:
The number 80 fits into 108 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 80 from 108, we get 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 80

Moving on to step 4:
80 goes into 287 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtract 240 from 287 to get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 80

Moving on to step 5:
472 divided by 80 is 5 with a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 1135.0
Subtracting 400 from 472 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 6:
The number 80 fits into 720 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1135.9
If we subtract 720 from 720, 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.

Let's proceed to step 7:
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: 1135.9
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.

Going ahead to step 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1135.9
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 result is 1135.9 with a remainder of 0.0.
