We look at the division of 447015 by 90 
Let's see how many times 90 fits into 447015.

Going ahead to step 1:
4 divided by 90 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Going ahead to step 2:
When dividing 44 by 90, we get 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 90

Step 3:
If we divide 447 by 90, we get 4 and a remainder of 87.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 87 after subtracting 360 from 447.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 90

Going ahead to step 4:
The number 90 fits into 870 9 times, leaving a remainder of 60.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 810 from 870 and we're left with 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 90

Going ahead to step 5:
The number 90 fits into 601 6 times, leaving a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 496.0
Deduct 540 from 601 and we're left with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 90

Let's proceed to step 6:
90 can be fit into 615 6 times, resulting in a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 4966.0
The remainder is 75 after subtracting 540 from 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
90 goes into 750 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 4966.8
If we subtract 720 from 750, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 4966.83
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 90 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 4966.833
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 4966.833, with a leftover of 0.003.
