395177 ÷ 90 
We want to divide 395177 by 90.

Let's proceed to step 1:
The number 90 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 90

On to step 2:
If we divide 39 by 90, we get 0 and 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.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 90

Advancing to step 3:
The number 90 fits into 395 4 times, leaving a remainder of 35.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 360 from 395, we get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 90

Advancing to step 4:
351 divided by 90 is 3 with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 270 from 351 leaves us with 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 90

Step 5:
90 can be fit into 817 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 439.0
If we take 810 away from 817, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 90

Let's proceed to step 6:
The number 90 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 4390.0
Subtract 0 from 77 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
90 can be fit into 770 8 times, resulting in a remainder of 50.
The next digit of our result is 8. 
Result so far: 4390.8
The remainder is 50 after subtracting 720 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4390.85
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4390.855
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 4390.855, and the remainder is 0.005.
