Let's divide 216615 by 90
We want to divide 216615 by 90.

Step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 90

Moving on to step 2:
90 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 90

Let's proceed to step 3:
If we divide 216 by 90, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 180 away from 216, we end up with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 90

Going ahead to step 4:
366 divided by 90 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 360 from 366 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 90

Step 5:
61 divided by 90 is 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 240.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 90

On to step 6:
The number 90 fits into 615 6 times, leaving a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 2406.0
Deduct 540 from 615 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 7:
90 goes into 750 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 2406.8
Subtract 720 from 750 to 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.

Going ahead to step 8:
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: 2406.83
Deduct 270 from 300 and we're left 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.

Going ahead to step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 2406.833
Deduct 270 from 300 and we're left 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.

In conclusion, the division gives 2406.833 with a balance of 0.003.
