215446 ÷ 66 
We want to divide 215446 by 66.

Moving on to step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 66

Advancing to step 2:
66 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 66

Let's proceed to step 3:
66 can be fit into 215 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 198 from 215, we get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 66

Let's proceed to step 4:
The number 66 fits into 174 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 42 after subtracting 132 from 174.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 66

Moving on to step 5:
When dividing 424 by 66, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 326.0
Subtracting 396 from 424 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 66

Let's proceed to step 6:
The number 66 fits into 286 4 times, leaving a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 3264.0
If we take 264 away from 286, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
66 goes into 220 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 3264.3
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
The number 66 fits into 220 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3264.33
If we take 198 away from 220, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 3264.33 with a remainder of 0.022.
