395672 ÷ 90 
Let's see how many times 90 fits into 395672.

On to step 1:
90 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
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

Advancing to step 2:
The number 90 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 90

Step 3:
When dividing 395 by 90, we get 4 with 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.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 90

Moving on to step 4:
90 goes into 356 3 times with a remainder of 86.
The next digit of our result is 3. 
Result so far: 43.0
If we take 270 away from 356, we end up with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 90

Going ahead to step 5:
90 can be fit into 867 9 times, resulting in a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 439.0
The remainder is 57 after subtracting 810 from 867.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 90

On to step 6:
572 divided by 90 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 4396.0
If we take 540 away from 572, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
If we divide 320 by 90, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 4396.3
Deduct 270 from 320 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.

Step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4396.35
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.

Advancing to step 9:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4396.355
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 4396.355, and the remainder is 0.005.
