We're dividing 343592 by 30 
Let's see how many times 30 fits into 343592.

On to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 30

Moving on to step 2:
If we divide 34 by 30, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 30 from 34 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

Going ahead to step 3:
If we divide 43 by 30, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 30 away from 43, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 30

Moving on to step 4:
If we divide 135 by 30, we get 4 and a remainder of 15.
The next digit of our result is 4. 
Result so far: 114.0
If we take 120 away from 135, we end up with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 30

Moving on to step 5:
30 goes into 159 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 1145.0
Deduct 150 from 159 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 30

Going ahead to step 6:
30 goes into 92 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 11453.0
If we subtract 90 from 92, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 30, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 11453.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 11453.06
Deduct 180 from 200 and we're left 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.

Advancing to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 11453.066
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.

The final outcome is 11453.066, with a leftover of 0.002.
