We look at the division of 442508 by 90 
We're looking to find how many times 90 goes into 442508.

Going ahead to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Step 2:
44 divided by 90 is 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 90

Moving on to step 3:
90 goes into 442 4 times with a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 442, we get 82.
Fetch the next digit (5) from the dividend, attach it to 82 and continue: 825 / 90

Advancing to step 4:
825 divided by 90 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 810 from 825 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 90

On to step 5:
If we divide 150 by 90, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 491.0
The remainder is 60 after subtracting 90 from 150.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 90

Moving on to step 6:
The number 90 fits into 608 6 times, leaving a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 4916.0
Subtract 540 from 608 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
When dividing 680 by 90, we get 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 4916.7
The remainder is 50 after subtracting 630 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4916.75
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4916.755
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 4916.755 with a remaining 0.005.
