We're dividing 872881 by 90 
Our goal is to divide 872881 by 90.

Step 1:
8 divided by 90 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 90

On to step 2:
90 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 90

Step 3:
If we divide 872 by 90, we get 9 and a remainder of 62.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 810 from 872, we get 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 90

Let's proceed to step 4:
90 goes into 628 6 times with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 540 from 628 to get 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 90

Step 5:
888 divided by 90 is 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 969.0
If we take 810 away from 888, we end up with 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 90

Moving on to step 6:
If we divide 781 by 90, we get 8 and a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 9698.0
Deduct 720 from 781 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
The number 90 fits into 610 6 times, leaving a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 9698.6
Deduct 540 from 610 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
700 divided by 90 is 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 9698.67
Subtract 630 from 700 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.

Going ahead to step 9:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 9698.677
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 9698.677, and the remainder is 0.007.
