We divide 346409 by 30
Our goal is to divide 346409 by 30.

Step 1:
The number 30 fits into 3 0 times, leaving 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.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 30

Moving on to step 2:
30 goes into 34 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 30 from 34, we get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 30

On to step 3:
46 divided by 30 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 16 after subtracting 30 from 46.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 30

Going ahead to step 4:
When dividing 164 by 30, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtracting 150 from 164 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 30

Going ahead to step 5:
The number 30 fits into 140 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1154.0
Subtract 120 from 140 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 30

Advancing to step 6:
When dividing 209 by 30, we get 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 11546.0
If we subtract 180 from 209, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
30 goes into 290 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 11546.9
If we subtract 270 from 290, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 11546.96
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 11546.966
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 11546.966 and a remainder of 0.002.
