145955 divided by 30 
Our goal is to divide 145955 by 30.

Let's proceed to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 30

Moving on to step 2:
If we divide 14 by 30, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 30

On to step 3:
30 goes into 145 4 times with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 120 from 145, we get 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 30

Going ahead to step 4:
30 can be fit into 259 8 times, resulting in a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 240 from 259 and we're left with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 30

Going ahead to step 5:
30 goes into 195 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 486.0
If we subtract 180 from 195, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 30

Moving on to step 6:
155 divided by 30 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4865.0
If we take 150 away from 155, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
30 can be fit into 50 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 4865.1
If we subtract 30 from 50, 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.

Let's proceed to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4865.16
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.

Going ahead to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 4865.166
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.

The final outcome is 4865.166, with a leftover of 0.002.
