We divide 409772 by 90
We want to divide 409772 by 90.

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
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 90

Let's proceed to step 2:
When dividing 40 by 90, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 90

Advancing to step 3:
409 divided by 90 is 4 with a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 360 from 409 leaves us with 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 90

Advancing to step 4:
90 can be fit into 497 5 times, resulting in a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 450 from 497 leaves us with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 90

Step 5:
When dividing 477 by 90, we get 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 455.0
The remainder is 27 after subtracting 450 from 477.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 90

Let's proceed to step 6:
272 divided by 90 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 4553.0
Deduct 270 from 272 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
90 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4553.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
90 goes into 200 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 4553.02
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 90 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 4553.022
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 4553.022 and a remainder of 0.002.
