216966 ÷ 90 
Let's see how many times 90 fits into 216966.

Step 1:
2 divided by 90 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 90

Going ahead to step 2:
90 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 90

Advancing to step 3:
90 goes into 216 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 180 from 216 and we're left with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 90

Let's proceed to step 4:
90 can be fit into 369 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 360 from 369 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 90

Moving on to step 5:
The number 90 fits into 96 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 241.0
Subtracting 90 from 96 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 90

Moving on to step 6:
When dividing 66 by 90, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 2410.0
Deduct 0 from 66 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
When dividing 660 by 90, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 2410.7
If we subtract 630 from 660, 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.

Going ahead to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2410.73
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.

Let's proceed to step 9:
90 goes into 300 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2410.733
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.

After the division, we end up with 2410.733 and a remainder of 0.003.
