We're dividing 481816 by 90 
We're looking to find how many times 90 goes into 481816.

Step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 90

Step 2:
If we divide 48 by 90, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 90

Going ahead to step 3:
The number 90 fits into 481 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 450 from 481 leaves us with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 90

On to step 4:
90 goes into 318 3 times with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 270 from 318 to get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 90

Moving on to step 5:
When dividing 481 by 90, we get 5 with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 535.0
If we take 450 away from 481, we end up with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 90

Going ahead to step 6:
If we divide 316 by 90, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 5353.0
If we take 270 away from 316, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
90 goes into 460 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5353.5
Subtract 450 from 460 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 5353.51
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 5353.511
Subtracting 90 from 100 leaves us 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.

The final outcome is 5353.511, with a leftover of 0.001.
