422412 divided by 90 
We're looking to find how many times 90 goes into 422412.

Going ahead to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 90

On to step 2:
90 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 90

Going ahead to step 3:
When dividing 422 by 90, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 360 away from 422, we end up with 62.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 90

Moving on to step 4:
90 can be fit into 624 6 times, resulting in a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 540 from 624, we get 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 90

Going ahead to step 5:
90 can be fit into 841 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 469.0
The remainder is 31 after subtracting 810 from 841.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 90

Going ahead to step 6:
When dividing 312 by 90, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 4693.0
The remainder is 42 after subtracting 270 from 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
90 can be fit into 420 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 4693.4
The remainder is 60 after subtracting 360 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 90 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 4693.46
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
600 divided by 90 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4693.466
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 4693.466 with a remaining 0.006.
