We divide 440905 by 90
We want to figure out the number of times 440905 can be divided by 90.

Advancing 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
If we subtract 0 from 4, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 90

Going ahead to step 2:
44 divided by 90 is 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 90

Let's proceed to step 3:
90 can be fit into 440 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 360 from 440, we get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 90

On to step 4:
90 goes into 809 8 times with a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 720 from 809 leaves us with 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 90

Moving on to step 5:
The number 90 fits into 890 9 times, leaving a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
If we subtract 810 from 890, we get 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 90

Moving on to step 6:
805 divided by 90 is 8 with a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 4898.0
Deduct 720 from 805 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 7:
When dividing 850 by 90, we get 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 4898.9
If we take 810 away from 850, we end up 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.

Advancing to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4898.94
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 4898.944
If we take 360 away from 400, we end up 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.

After the division, we end up with 4898.944 and a remainder of 0.004.
