We divide 438022 by 90
We want to figure out the number of times 438022 can be divided by 90.

Moving on to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 90

On to step 2:
90 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 90

Advancing to step 3:
The number 90 fits into 438 4 times, leaving a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 360 from 438 to get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 90

Advancing to step 4:
90 can be fit into 780 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 720 away from 780, we end up with 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 90

Moving on to step 5:
When dividing 602 by 90, we get 6 with a remainder of 62.
The next digit of our result is 6. 
Result so far: 486.0
Subtracting 540 from 602 leaves us with 62.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 90

Moving on to step 6:
90 can be fit into 622 6 times, resulting in a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 4866.0
If we take 540 away from 622, we end up with 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 7:
90 can be fit into 820 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 4866.9
Deduct 810 from 820 and we're left 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.

On to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 4866.91
Deduct 90 from 100 and we're left 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.

Advancing to step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 4866.911
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 4866.911 with a balance of 0.001.
