We're dividing 446007 by 90 
We want to divide 446007 by 90.

Let's proceed to step 1:
4 divided by 90 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 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
If we take 0 away from 44, we end up with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 90

On to step 3:
90 goes into 446 4 times with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 360 away from 446, we end up with 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 90

Moving on to step 4:
860 divided by 90 is 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 810 away from 860, we end up with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 90

Moving on to step 5:
When dividing 500 by 90, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 495.0
If we subtract 450 from 500, we get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 90

Moving on to step 6:
When dividing 507 by 90, we get 5 with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 4955.0
Subtract 450 from 507 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
If we divide 570 by 90, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 4955.6
Subtracting 540 from 570 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.

Going ahead to step 8:
90 goes into 300 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 4955.63
Subtract 270 from 300 to 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.

Let's proceed to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 4955.633
If we take 270 away from 300, we end up 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 4955.633, with a leftover of 0.003.
