We divide 30300270 by 215
Our goal is to divide 30300270 by 215.

Going ahead to step 1:
The number 215 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 215

On to step 2:
215 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 215

On to step 3:
215 can be fit into 303 1 times, resulting in a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 215 from 303, we get 88.
Grab the next digit (0) from the dividend, add it to 88, then carry on: 880 / 215

Let's proceed to step 4:
215 can be fit into 880 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 20 after subtracting 860 from 880.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 215

Advancing to step 5:
The number 215 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtracting 0 from 200 leaves us with 200.
Bring next digit (2) of the dividend behind the 200 and repeat the process: 2002 / 215

Going ahead to step 6:
The number 215 fits into 2002 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 1409.0
Subtract 1935 from 2002 to get 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 215

Going ahead to step 7:
When dividing 677 by 215, we get 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 14093.0
If we subtract 645 from 677, we get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 215

Step 8:
320 divided by 215 is 1 with a remainder of 105.
The next digit of our result is 1. 
Result so far: 140931.0
Subtract 215 from 320 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
1050 divided by 215 is 4 with a remainder of 190.
The number 4 becomes the next digit in our result. 
Result so far: 140931.4
Subtracting 860 from 1050 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
215 can be fit into 1900 8 times, resulting in a remainder of 180.
The next digit of our result is 8. 
Result so far: 140931.48
If we subtract 1720 from 1900, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
The number 215 fits into 1800 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 140931.488
Subtract 1720 from 1800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 140931.488, with a leftover of 0.008.
