407490 divided by 90 
Our goal is to divide 407490 by 90.

Let's proceed to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 90

Advancing to step 2:
40 divided by 90 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 90

Going ahead to step 3:
90 goes into 407 4 times with a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 360 from 407 leaves us with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 90

Let's proceed to step 4:
The number 90 fits into 474 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 24 after subtracting 450 from 474.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 90

Advancing to step 5:
The number 90 fits into 249 2 times, leaving a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 452.0
The remainder is 69 after subtracting 180 from 249.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 90

Advancing to step 6:
If we divide 690 by 90, we get 7 and a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 4527.0
Deduct 630 from 690 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 90, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 4527.6
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 4527.66
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 4527.66 with a balance of 0.06.
