20879 divided by 66 
We're looking to find how many times 66 goes into 20879.

On to step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 66

Moving on to step 2:
If we divide 20 by 66, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 66

Step 3:
66 can be fit into 208 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 10 after subtracting 198 from 208.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 66

Moving on to step 4:
66 can be fit into 107 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 41 after subtracting 66 from 107.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 66

Going ahead to step 5:
66 goes into 419 6 times with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 316.0
The remainder is 23 after subtracting 396 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 6:
66 can be fit into 230 3 times, resulting in a remainder of 32.
The next digit of our result is 3. 
Result so far: 316.3
If we take 198 away from 230, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
If we divide 320 by 66, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 316.34
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
66 goes into 560 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 316.348
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 66, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 316.3484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 316.34848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 66, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 316.348484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
560 divided by 66 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 316.3484848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
66 goes into 320 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 316.34848484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 316.34848484 with a remaining 5.6e-08.
