395986 divided by 90 
Our goal is to divide 395986 by 90.

On to step 1:
3 divided by 90 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 90

Let's proceed to step 2:
When dividing 39 by 90, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 90

On to step 3:
90 can be fit into 395 4 times, resulting in a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 360 away from 395, we end up with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 90

Advancing to step 4:
The number 90 fits into 359 3 times, leaving a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 270 from 359 leaves us with 89.
Append the next digit (8) from the dividend to 89 and continue with: 898 / 90

Moving on to step 5:
If we divide 898 by 90, we get 9 and a remainder of 88.
The next digit of our result is 9. 
Result so far: 439.0
The remainder is 88 after subtracting 810 from 898.
Fetch the next digit (6) from the dividend, attach it to 88 and continue: 886 / 90

Let's proceed to step 6:
90 goes into 886 9 times with a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 4399.0
If we subtract 810 from 886, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
90 can be fit into 760 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 4399.8
Subtracting 720 from 760 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
90 goes into 400 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 4399.84
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4399.844
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 4399.844 with a balance of 0.004.
