Let's divide 342661 by 66
We're looking to find how many times 66 goes into 342661.

Step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 66

Step 2:
The number 66 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 66

Advancing to step 3:
If we divide 342 by 66, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 330 from 342 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 66

On to step 4:
126 divided by 66 is 1 with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 66 from 126 leaves us with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 66

Moving on to step 5:
606 divided by 66 is 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 519.0
Subtract 594 from 606 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 66

Let's proceed to step 6:
The number 66 fits into 121 1 times, leaving a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 5191.0
If we subtract 66 from 121, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
When dividing 550 by 66, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 5191.8
If we take 528 away from 550, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 66 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 5191.83
Subtract 198 from 220 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 66, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 5191.833
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 5191.833 with a remaining 0.0022.
