172343 divided by 30 
Let's see how many times 30 fits into 172343.

Moving on to step 1:
1 divided by 30 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 30

Let's proceed to step 2:
30 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 30

Step 3:
30 can be fit into 172 5 times, resulting in a remainder of 22.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 150 from 172 leaves us with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 30

Going ahead to step 4:
30 can be fit into 223 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 210 from 223, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 30

Step 5:
The number 30 fits into 134 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 574.0
If we take 120 away from 134, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 30

Advancing to step 6:
If we divide 143 by 30, we get 4 and a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 5744.0
Deduct 120 from 143 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 30, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 5744.7
If we subtract 210 from 230, 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.

Advancing to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 5744.76
The remainder is 20 after subtracting 180 from 200.
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 9:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 5744.766
If we subtract 180 from 200, 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.

Our division results in 5744.766 with a remaining 0.002.
