We look at the division of 442642 by 90 
We want to divide 442642 by 90.

Let's proceed to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 90

Let's proceed to step 2:
When dividing 44 by 90, we get 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 90

Step 3:
If we divide 442 by 90, we get 4 and a remainder of 82.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 360 from 442, we get 82.
Bring next digit (6) of the dividend behind the 82 and repeat the process: 826 / 90

On to step 4:
When dividing 826 by 90, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 810 away from 826, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 90

Step 5:
If we divide 164 by 90, we get 1 and a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 491.0
Subtracting 90 from 164 leaves us with 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 90

Step 6:
If we divide 742 by 90, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 4918.0
If we take 720 away from 742, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
If we divide 220 by 90, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 4918.2
If we subtract 180 from 220, 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.

Let's proceed to step 8:
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: 4918.24
Deduct 360 from 400 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.

Advancing to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 4918.244
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.

In conclusion, the division gives 4918.244 with a balance of 0.004.
