Let's divide 42023650 by 90
We want to divide 42023650 by 90.

Going ahead to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 90

Let's proceed to step 2:
When dividing 42 by 90, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 90

Let's proceed to step 3:
90 goes into 420 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 60 after subtracting 360 from 420.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 90

Let's proceed to step 4:
If we divide 602 by 90, we get 6 and a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtract 540 from 602 to get 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 90

Advancing to step 5:
90 can be fit into 623 6 times, resulting in a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 466.0
If we take 540 away from 623, we end up with 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 90

Step 6:
If we divide 836 by 90, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 4669.0
Subtract 810 from 836 to get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 90

Advancing to step 7:
If we divide 265 by 90, we get 2 and a remainder of 85.
The next digit of our result is 2. 
Result so far: 46692.0
Deduct 180 from 265 and we're left with 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 90

Step 8:
If we divide 850 by 90, we get 9 and a remainder of 40.
The next digit of our result is 9. 
Result so far: 466929.0
If we subtract 810 from 850, 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.

On to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 466929.4
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 466929.44
The remainder is 40 after subtracting 360 from 400.
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 466929.44 with a balance of 0.04.
