We're dividing 143979 by 66 
We're looking to find how many times 66 goes into 143979.

Moving on to step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 66

Step 2:
66 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 66

Let's proceed to step 3:
143 divided by 66 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 132 away from 143, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 66

Going ahead to step 4:
66 goes into 119 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 66 from 119, we get 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 66

Moving on to step 5:
537 divided by 66 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
The remainder is 9 after subtracting 528 from 537.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 66

Going ahead to step 6:
99 divided by 66 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 2181.0
Subtract 66 from 99 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
66 goes into 330 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2181.5
Subtract 330 from 330 to get 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:
66 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2181.5
The remainder is 0 after subtracting 0 from 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 9:
66 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2181.5
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.

In conclusion, the division gives 2181.5 with a balance of 0.0.
