30193139 ÷ 310 
We want to figure out the number of times 30193139 can be divided by 310.

Going ahead to step 1:
310 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 310

Moving on to step 2:
310 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 310

Let's proceed to step 3:
310 goes into 301 0 times with a remainder of 301.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 301, we get 301.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 310

Moving on to step 4:
When dividing 3019 by 310, we get 9 with a remainder of 229.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 229 after subtracting 2790 from 3019.
Grab the next digit (3) from the dividend, add it to 229, then carry on: 2293 / 310

Step 5:
When dividing 2293 by 310, we get 7 with a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 2170 from 2293 leaves us with 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 310

Step 6:
When dividing 1231 by 310, we get 3 with a remainder of 301.
The number 3 becomes the next digit in our result. 
Result so far: 973.0
Subtracting 930 from 1231 leaves us with 301.
Append the next digit (3) from the dividend to 301 and continue with: 3013 / 310

Step 7:
If we divide 3013 by 310, we get 9 and a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 9739.0
Deduct 2790 from 3013 and we're left with 223.
Include the next digit (9) from the dividend after 223, then repeat: 2239 / 310

Step 8:
2239 divided by 310 is 7 with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 97397.0
Subtract 2170 from 2239 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
If we divide 690 by 310, we get 2 and a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 97397.2
If we subtract 620 from 690, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
310 can be fit into 700 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 97397.22
The remainder is 80 after subtracting 620 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 97397.22 with a balance of 0.08.
