Let's divide 215604 by 66
We want to figure out the number of times 215604 can be divided by 66.

Going ahead to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 66

Going ahead to step 2:
If we divide 21 by 66, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 66

Let's proceed to step 3:
The number 66 fits into 215 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 198 from 215 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 66

Advancing to step 4:
66 can be fit into 176 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 132 from 176, we get 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 66

Going ahead to step 5:
440 divided by 66 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 326.0
Subtracting 396 from 440 leaves us with 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 66

On to step 6:
If we divide 444 by 66, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 3266.0
Subtracting 396 from 444 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
The number 66 fits into 480 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 3266.7
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 66 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 3266.72
If we subtract 132 from 180, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
66 can be fit into 480 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3266.727
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
66 can be fit into 180 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 3266.7272
Subtracting 132 from 180 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
When dividing 480 by 66, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3266.72727
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
180 divided by 66 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 3266.727272
The remainder is 48 after subtracting 132 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
66 goes into 480 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 3266.7272727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
66 goes into 180 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 3266.72727272
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 3266.72727272 with a balance of 4.8e-08.
