407731 ÷ 90 
We want to divide 407731 by 90.

Advancing to step 1:
90 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 90

Moving on 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
If we take 0 away from 40, we end up with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 90

Step 3:
The number 90 fits into 407 4 times, leaving a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 407, we get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 90

Going ahead to step 4:
90 can be fit into 477 5 times, resulting in a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 450 from 477 and we're left with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 90

Let's proceed to step 5:
If we divide 273 by 90, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Subtracting 270 from 273 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 90

Advancing to step 6:
If we divide 31 by 90, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 4530.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
If we divide 310 by 90, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 4530.3
Deduct 270 from 310 and we're left 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.

Step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 4530.34
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.

Moving on to step 9:
90 goes into 400 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 4530.344
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 4530.344 with a balance of 0.004.
