We look at the division of 902688 by 90 
We want to divide 902688 by 90.

Let's proceed to step 1:
9 divided by 90 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 90

Going ahead to step 2:
90 goes into 90 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 90

On to step 3:
90 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 90

Moving on to step 4:
26 divided by 90 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 90

On to step 5:
If we divide 268 by 90, we get 2 and a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 1002.0
Subtracting 180 from 268 leaves us with 88.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 90

Moving on to step 6:
90 goes into 888 9 times with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 10029.0
Subtracting 810 from 888 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
When dividing 780 by 90, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 10029.8
If we subtract 720 from 780, 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.

Let's proceed to step 8:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 10029.86
Subtracting 540 from 600 leaves us 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.

Going ahead to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 10029.866
Subtracting 540 from 600 leaves us 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.

The final outcome is 10029.866, with a leftover of 0.006.
