We divide 344399 by 66
We want to figure out the number of times 344399 can be divided by 66.

Going ahead to step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 66

Step 2:
34 divided by 66 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 66

Moving on to step 3:
344 divided by 66 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 330 from 344, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 66

Going ahead to step 4:
66 can be fit into 143 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 11 after subtracting 132 from 143.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 66

Going ahead to step 5:
66 can be fit into 119 1 times, resulting in a remainder of 53.
The next digit of our result is 1. 
Result so far: 521.0
If we subtract 66 from 119, we get 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 66

Going ahead to step 6:
The number 66 fits into 539 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 5218.0
Subtracting 528 from 539 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
66 can be fit into 110 1 times, resulting in a remainder of 44.
The next digit of our result is 1. 
Result so far: 5218.1
The remainder is 44 after subtracting 66 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
The number 66 fits into 440 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 5218.16
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
440 divided by 66 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5218.166
Subtract 396 from 440 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 5218.166 with a remaining 0.0044.
