We divide 345571 by 66
We want to divide 345571 by 66.

Step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 66

Let's proceed to step 2:
The number 66 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 66

On to step 3:
If we divide 345 by 66, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 330 from 345 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 66

Moving on to step 4:
155 divided by 66 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 132 from 155, we get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 66

Advancing to step 5:
The number 66 fits into 237 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 523.0
Deduct 198 from 237 and we're left with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 66

On to step 6:
66 can be fit into 391 5 times, resulting in a remainder of 61.
The next digit of our result is 5. 
Result so far: 5235.0
Subtracting 330 from 391 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
66 can be fit into 610 9 times, resulting in a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 5235.9
Deduct 594 from 610 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5235.92
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
66 goes into 280 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 5235.924
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 66, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 5235.9242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5235.92424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
160 divided by 66 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 5235.924242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
66 goes into 280 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5235.9242424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5235.92424242
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 5235.92424242 and a remainder of 2.8e-08.
