872556 divided by 90 
We want to figure out the number of times 872556 can be divided by 90.

Moving on to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 90

Advancing to step 2:
The number 90 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 90

On to step 3:
The number 90 fits into 872 9 times, leaving a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 810 from 872 to get 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 90

Moving on to step 4:
90 goes into 625 6 times with a remainder of 85.
The next digit of our result is 6. 
Result so far: 96.0
If we take 540 away from 625, we end up with 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 90

Let's proceed to step 5:
When dividing 855 by 90, we get 9 with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 969.0
Subtracting 810 from 855 leaves us with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 90

Let's proceed to step 6:
90 goes into 456 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 9695.0
The remainder is 6 after subtracting 450 from 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 90 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 9695.0
If we take 0 away from 60, we end up 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.

On to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 9695.06
Subtract 540 from 600 to 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.

Let's proceed to step 9:
90 goes into 600 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 9695.066
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 9695.066 with a remaining 0.006.
