We divide 340671 by 30
Our goal is to divide 340671 by 30.

Let's proceed to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
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 / 30

Moving on to step 2:
34 divided by 30 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 30 from 34, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 30

Moving on to step 3:
40 divided by 30 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 30 away from 40, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 30

Going ahead to step 4:
30 goes into 106 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
The remainder is 16 after subtracting 90 from 106.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 30

Step 5:
30 can be fit into 167 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1135.0
Subtracting 150 from 167 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 30

On to step 6:
When dividing 171 by 30, we get 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 11355.0
If we subtract 150 from 171, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 30, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 11355.7
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11355.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11355.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11355.7, with a leftover of 0.0.
