401005 ÷ 90 
We want to divide 401005 by 90.

Advancing to step 1:
90 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 90

Moving on to step 2:
When dividing 40 by 90, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 90

Moving on to step 3:
The number 90 fits into 401 4 times, leaving a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 401, we get 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 90

Step 4:
If we divide 410 by 90, we get 4 and a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 360 from 410 to get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 90

Moving on to step 5:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 445.0
If we subtract 450 from 500, we get 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 90

Step 6:
If we divide 505 by 90, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4455.0
If we take 450 away from 505, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
If we divide 550 by 90, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4455.6
If we take 540 away from 550, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 4455.61
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 4455.611
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 4455.611 with a balance of 0.001.
