42382 divided by 90 
We want to figure out the number of times 42382 can be divided by 90.

Step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 90

Advancing to step 2:
42 divided by 90 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 90

Going ahead to step 3:
90 goes into 423 4 times with a remainder of 63.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 360 from 423 and we're left with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 90

Going ahead to step 4:
When dividing 638 by 90, we get 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 630 away from 638, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 90

Moving on to step 5:
The number 90 fits into 82 0 times, leaving a remainder of 82.
The next digit of our result is 0. 
Result so far: 470.0
Subtract 0 from 82 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 6:
When dividing 820 by 90, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 470.9
If we take 810 away from 820, 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.

Step 7:
If we divide 100 by 90, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 470.91
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 90 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 470.911
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 470.911 and a remainder of 0.001.
