216552 divided by 90 
Our goal is to divide 216552 by 90.

Step 1:
90 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 90

Step 2:
90 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 90

Step 3:
90 goes into 216 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 180 from 216, we get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 90

Moving on to step 4:
If we divide 365 by 90, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 360 away from 365, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 90

Moving on to step 5:
90 goes into 55 0 times with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 240.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 90

Let's proceed to step 6:
90 goes into 552 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 2406.0
The remainder is 12 after subtracting 540 from 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
The number 90 fits into 120 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 2406.1
If we subtract 90 from 120, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 2406.13
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 2406.133
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 2406.133, with a leftover of 0.003.
