Let's divide 392884 by 90
We want to figure out the number of times 392884 can be divided by 90.

Moving on to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 90

On to step 2:
90 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 90

Moving on to step 3:
90 can be fit into 392 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 392, we get 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 90

On to step 4:
If we divide 328 by 90, we get 3 and a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 270 from 328 and we're left with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 90

On to step 5:
588 divided by 90 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 436.0
Subtracting 540 from 588 leaves us with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 90

Going ahead to step 6:
484 divided by 90 is 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 4365.0
If we subtract 450 from 484, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
90 goes into 340 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 4365.3
If we subtract 270 from 340, we 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.

Let's proceed to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 4365.37
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.

Let's proceed to step 9:
If we divide 700 by 90, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 4365.377
The remainder is 70 after subtracting 630 from 700.
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 4365.377, and the remainder is 0.007.
