465223 ÷ 90 
Our goal is to divide 465223 by 90.

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
The remainder is 4 after subtracting 0 from 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 90

Advancing to step 2:
90 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 90

Step 3:
If we divide 465 by 90, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 450 from 465 leaves us with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 90

Advancing to step 4:
152 divided by 90 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 51.0
Deduct 90 from 152 and we're left with 62.
Include the next digit (2) from the dividend after 62, then repeat: 622 / 90

Step 5:
622 divided by 90 is 6 with a remainder of 82.
The next digit of our result is 6. 
Result so far: 516.0
Subtract 540 from 622 to get 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 90

Going ahead to step 6:
90 goes into 823 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 5169.0
If we take 810 away from 823, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 90, we get 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 5169.1
If we take 90 away from 130, 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.

Going ahead to step 8:
90 goes into 400 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 5169.14
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 5169.144
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.

The final outcome is 5169.144, with a leftover of 0.004.
