We look at the division of 345450 by 66 
We want to divide 345450 by 66.

Advancing to step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 66

Step 2:
66 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 66

Step 3:
The number 66 fits into 345 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 330 from 345, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 66

Let's proceed to step 4:
66 goes into 154 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 132 from 154 leaves us with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 66

On to step 5:
66 goes into 225 3 times with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 523.0
Subtract 198 from 225 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 66

On to step 6:
270 divided by 66 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 5234.0
Subtract 264 from 270 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 66, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5234.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 5234.09
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
66 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5234.09
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
66 goes into 600 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 5234.0909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5234.0909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 66, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5234.090909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5234.090909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 66 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5234.09090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 5234.09090909 with a remainder of 6e-09.
