We look at the division of 406024 by 90 
Let's see how many times 90 fits into 406024.

Step 1:
4 divided by 90 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 90

Going ahead to step 2:
40 divided by 90 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 90

Moving on to step 3:
If we divide 406 by 90, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 46 after subtracting 360 from 406.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 90

Moving on to step 4:
The number 90 fits into 460 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 450 away from 460, we end up with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 90

On to step 5:
102 divided by 90 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 451.0
If we subtract 90 from 102, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 90

Moving on to step 6:
The number 90 fits into 124 1 times, leaving a remainder of 34.
The next digit of our result is 1. 
Result so far: 4511.0
Deduct 90 from 124 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
90 can be fit into 340 3 times, resulting in a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 4511.3
Deduct 270 from 340 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 4511.37
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 4511.377
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 4511.377 and a remainder of 0.007.
