We're dividing 405853 by 66 
We're looking to find how many times 66 goes into 405853.

Moving on to step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 66

Advancing to step 2:
If we divide 40 by 66, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 66

Let's proceed to step 3:
The number 66 fits into 405 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 396 from 405, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 66

Advancing to step 4:
The number 66 fits into 98 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtracting 66 from 98 leaves us with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 66

Let's proceed to step 5:
The number 66 fits into 325 4 times, leaving a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 614.0
The remainder is 61 after subtracting 264 from 325.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 66

Advancing to step 6:
The number 66 fits into 613 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 6149.0
If we subtract 594 from 613, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
66 goes into 190 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 6149.2
Subtract 132 from 190 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
66 can be fit into 580 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 6149.28
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
66 goes into 520 7 times with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 6149.287
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
When dividing 580 by 66, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 6149.2878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
If we divide 520 by 66, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 6149.28787
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 6149.287878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
If we divide 520 by 66, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 6149.2878787
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 6149.28787878
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 6149.28787878 with a remainder of 5.2e-08.
