Let's divide 345890 by 30
We want to divide 345890 by 30.

Step 1:
When dividing 3 by 30, we get 0 with 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.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 30

Going ahead to step 2:
If we divide 34 by 30, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 34 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 30

Advancing to step 3:
When dividing 45 by 30, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 30 from 45 leaves us with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 30

Step 4:
When dividing 158 by 30, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 150 from 158 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 30

Let's proceed to step 5:
If we divide 89 by 30, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 1152.0
Deduct 60 from 89 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 30

Let's proceed to step 6:
If we divide 290 by 30, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 11529.0
If we take 270 away from 290, 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 7:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 11529.6
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.

On to step 8:
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: 11529.66
Subtract 180 from 200 to 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.

In conclusion, the division gives 11529.66 with a balance of 0.02.
