Let's divide 319185 by 30
Let's see how many times 30 fits into 319185.

On to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 30

Going ahead to step 2:
30 can be fit into 31 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 30 from 31 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 30

Let's proceed to step 3:
If we divide 19 by 30, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 30

Let's proceed to step 4:
The number 30 fits into 191 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we subtract 180 from 191, we get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 30

Moving on to step 5:
118 divided by 30 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 1063.0
If we take 90 away from 118, we end up with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 30

Step 6:
When dividing 285 by 30, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 10639.0
The remainder is 15 after subtracting 270 from 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
30 can be fit into 150 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10639.5
If we subtract 150 from 150, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10639.5
Deduct 0 from 0 and we're left 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.

Advancing to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10639.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10639.5, with a leftover of 0.0.
