Let's divide 398708 by 90
We're looking to find how many times 90 goes into 398708.

Let's proceed to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 90

Advancing to step 2:
When dividing 39 by 90, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 90

Moving on to step 3:
If we divide 398 by 90, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 360 from 398, we get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 90

Step 4:
If we divide 387 by 90, we get 4 and a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 360 from 387, we get 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 90

On to step 5:
When dividing 270 by 90, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 443.0
If we take 270 away from 270, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 90

Moving on to step 6:
When dividing 8 by 90, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 4430.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
90 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4430.0
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 4430.08
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 4430.088
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 4430.088 with a balance of 0.008.
