We divide 339509 by 66
We want to divide 339509 by 66.

Advancing to step 1:
If we divide 3 by 66, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 66

Advancing to step 2:
When dividing 33 by 66, we get 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 66

Let's proceed to step 3:
If we divide 339 by 66, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 330 from 339 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 66

Advancing to step 4:
95 divided by 66 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 66 from 95, we get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 66

On to step 5:
If we divide 290 by 66, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 514.0
The remainder is 26 after subtracting 264 from 290.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 66

Let's proceed to step 6:
The number 66 fits into 269 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 5144.0
Subtract 264 from 269 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 66 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5144.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
66 goes into 500 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 5144.07
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
If we divide 380 by 66, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 5144.075
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 5144.0757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
When dividing 380 by 66, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5144.07575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 5144.075757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 66, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 5144.0757575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
If we divide 500 by 66, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 5144.07575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 5144.07575757 with a remaining 3.8e-08.
