Let's divide 350439 by 66
We want to figure out the number of times 350439 can be divided by 66.

On to step 1:
66 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 66

Advancing to step 2:
66 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 66

Step 3:
If we divide 350 by 66, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 20 after subtracting 330 from 350.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 66

Going ahead to step 4:
If we divide 204 by 66, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 198 from 204, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 66

Moving on to step 5:
The number 66 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 530.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 66

Moving on to step 6:
If we divide 639 by 66, we get 9 and a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 5309.0
Deduct 594 from 639 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
66 goes into 450 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 5309.6
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
540 divided by 66 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5309.68
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 5309.681
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
540 divided by 66 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5309.6818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 5309.68181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
540 divided by 66 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5309.681818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 5309.6818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
540 divided by 66 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5309.68181818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 5309.68181818 with a remaining 1.2e-08.
