We're dividing 30570 by 3 
We want to figure out the number of times 30570 can be divided by 3.

Step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Step 2:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Advancing to step 3:
3 goes into 5 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 3 from 5 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

On to step 4:
27 divided by 3 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1019.0
The remainder is 0 after subtracting 27 from 27.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Going ahead to step 5:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10190.0
Subtract 0 from 0 to 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.

Advancing to step 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10190.0
If we take 0 away from 0, we end up 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.

On to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10190.0
Subtract 0 from 0 to 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 10190.0, with a leftover of 0.0.
