215457 divided by 66 
Let's see how many times 66 fits into 215457.

Advancing to step 1:
2 divided by 66 is 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.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 66

Let's proceed to step 2:
66 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 66

Let's proceed to step 3:
When dividing 215 by 66, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 17 after subtracting 198 from 215.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 66

Moving on to step 4:
66 can be fit into 174 2 times, resulting in a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 132 from 174, we get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 66

On to step 5:
If we divide 425 by 66, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 326.0
Subtracting 396 from 425 leaves us with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 66

On to step 6:
66 goes into 297 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 3264.0
The remainder is 33 after subtracting 264 from 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
66 goes into 330 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3264.5
Deduct 330 from 330 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 66 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3264.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
66 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3264.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3264.5, and the remainder is 0.0.
