We look at the division of 923208 by 90 
We're looking to find how many times 90 goes into 923208.

Step 1:
90 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 90

Moving on to step 2:
90 goes into 92 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 90 from 92 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 90

Going ahead to step 3:
23 divided by 90 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 23, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 90

Let's proceed to step 4:
90 goes into 232 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we take 180 away from 232, we end up with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 90

Moving on to step 5:
If we divide 520 by 90, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1025.0
The remainder is 70 after subtracting 450 from 520.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 90

On to step 6:
90 can be fit into 708 7 times, resulting in a remainder of 78.
The next digit of our result is 7. 
Result so far: 10257.0
If we subtract 630 from 708, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
The number 90 fits into 780 8 times, leaving a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 10257.8
The remainder is 60 after subtracting 720 from 780.
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.
Put 6 as the next digit of the answer. 
Result so far: 10257.86
If we take 540 away from 600, 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.

Step 9:
90 goes into 600 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 10257.866
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.

The quotient of the division is 10257.866, and the remainder is 0.006.
