We look at the division of 340221 by 66 
Let's see how many times 66 fits into 340221.

Let's proceed to step 1:
3 divided by 66 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 66

Let's proceed to step 2:
66 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 66

Moving on to step 3:
The number 66 fits into 340 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 330 from 340 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 66

Advancing to step 4:
If we divide 102 by 66, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 36 after subtracting 66 from 102.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 66

Let's proceed to step 5:
66 can be fit into 362 5 times, resulting in a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 515.0
If we subtract 330 from 362, we get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 66

On to step 6:
The number 66 fits into 321 4 times, leaving a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 5154.0
Deduct 264 from 321 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
If we divide 570 by 66, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 5154.8
If we subtract 528 from 570, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
420 divided by 66 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 5154.86
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 5154.863
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 66 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5154.8636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 5154.86363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 5154.863636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
When dividing 240 by 66, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 5154.8636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
When dividing 420 by 66, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5154.86363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 5154.86363636, with a leftover of 2.4e-08.
