439925 divided by 66 
We want to divide 439925 by 66.

Going ahead to step 1:
If we divide 4 by 66, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 66

Step 2:
43 divided by 66 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 66

On to step 3:
66 can be fit into 439 6 times, resulting in a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 396 from 439, we get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 66

Moving on to step 4:
When dividing 439 by 66, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 396 from 439 leaves us with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 66

Step 5:
432 divided by 66 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
Subtract 396 from 432 to get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 66

Moving on to step 6:
365 divided by 66 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 6665.0
Deduct 330 from 365 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
The number 66 fits into 350 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 6665.5
Subtract 330 from 350 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 66, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 6665.53
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 66 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6665.53
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 66 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 6665.5303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 66 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6665.5303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 66 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 6665.530303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 66, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6665.530303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 66, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 6665.53030303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 6665.53030303, with a leftover of 2e-09.
