153949 ÷ 66 
Let's see how many times 66 fits into 153949.

Advancing to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 66

Going ahead to step 2:
66 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 66

On to step 3:
When dividing 153 by 66, we get 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 132 from 153 to get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 66

Moving on to step 4:
219 divided by 66 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 198 from 219 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 66

Let's proceed to step 5:
66 can be fit into 214 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 233.0
The remainder is 16 after subtracting 198 from 214.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 66

Let's proceed to step 6:
If we divide 169 by 66, we get 2 and a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2332.0
If we take 132 away from 169, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
If we divide 370 by 66, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 2332.5
If we subtract 330 from 370, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
66 goes into 400 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2332.56
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2332.56
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 66 fits into 400 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2332.5606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 66, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2332.5606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2332.560606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
40 divided by 66 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2332.560606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
When dividing 400 by 66, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2332.56060606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 2332.56060606 with a balance of 4e-09.
