339274 ÷ 66 
Let's see how many times 66 fits into 339274.

Step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
The next digit of our result is 0. 
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

On to step 2:
When dividing 33 by 66, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 66

Step 3:
When dividing 339 by 66, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 330 away from 339, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 66

On to step 4:
66 goes into 92 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 51.0
If we take 66 away from 92, we end up with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 66

On to step 5:
If we divide 267 by 66, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 514.0
The remainder is 3 after subtracting 264 from 267.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 66

Advancing to step 6:
34 divided by 66 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 5140.0
If we subtract 0 from 34, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
When dividing 340 by 66, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5140.5
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 66, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 5140.51
If we take 66 away from 100, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
66 goes into 340 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5140.515
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 5140.5151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
66 can be fit into 340 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5140.51515
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 66, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 5140.515151
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
When dividing 340 by 66, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5140.5151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
66 goes into 100 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 5140.51515151
If we take 66 away from 100, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 5140.51515151, with a leftover of 3.4e-08.
