We divide 392868 by 90
We want to divide 392868 by 90.

Advancing to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 90

Let's proceed to step 2:
The number 90 fits into 39 0 times, leaving 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.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 90

On to step 3:
When dividing 392 by 90, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 360 away from 392, we end up with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 90

Moving on to step 4:
When dividing 328 by 90, we get 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 270 from 328 and we're left with 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 90

Going ahead to step 5:
586 divided by 90 is 6 with a remainder of 46.
The next digit of our result is 6. 
Result so far: 436.0
The remainder is 46 after subtracting 540 from 586.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 90

Let's proceed to step 6:
The number 90 fits into 468 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 4365.0
If we take 450 away from 468, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
The number 90 fits into 180 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4365.2
Subtract 180 from 180 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4365.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4365.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4365.2 with a remainder of 0.0.
