342690 ÷ 30 
We want to divide 342690 by 30.

Let's proceed to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 30

Moving on to step 2:
The number 30 fits into 34 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 30 from 34.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 30

Let's proceed to step 3:
When dividing 42 by 30, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 30 from 42 leaves us with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 30

Going ahead to step 4:
30 goes into 126 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 6 after subtracting 120 from 126.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 30

On to step 5:
When dividing 69 by 30, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 1142.0
Deduct 60 from 69 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 30

Moving on to step 6:
If we divide 90 by 30, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 11423.0
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11423.0
Subtracting 0 from 0 leaves us 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.

Moving on to step 8:
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: 11423.0
Subtracting 0 from 0 leaves us 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.

Our division results in 11423.0 with a remaining 0.0.
