Let's divide 30755302 by 815
We're looking to find how many times 815 goes into 30755302.

Step 1:
When dividing 3 by 815, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 815

Step 2:
815 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 815

Advancing to step 3:
If we divide 307 by 815, we get 0 and a remainder of 307.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 307 leaves us with 307.
Include the next digit (5) from the dividend after 307, then repeat: 3075 / 815

Step 4:
3075 divided by 815 is 3 with a remainder of 630.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 630 after subtracting 2445 from 3075.
Fetch the next digit (5) from the dividend, attach it to 630 and continue: 6305 / 815

Going ahead to step 5:
If we divide 6305 by 815, we get 7 and a remainder of 600.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 5705 from 6305, we get 600.
Take the next digit (3) from the dividend and append it to 600, then repeat: 6003 / 815

Step 6:
If we divide 6003 by 815, we get 7 and a remainder of 298.
Put 7 as the next digit of the answer. 
Result so far: 377.0
If we subtract 5705 from 6003, we get 298.
Fetch the next digit (0) from the dividend, attach it to 298 and continue: 2980 / 815

Going ahead to step 7:
815 goes into 2980 3 times with a remainder of 535.
Record the quotient 3 as the next digit in the result. 
Result so far: 3773.0
If we subtract 2445 from 2980, we get 535.
Include the next digit (2) from the dividend after 535, then repeat: 5352 / 815

Advancing to step 8:
815 can be fit into 5352 6 times, resulting in a remainder of 462.
The number 6 becomes the next digit in our result. 
Result so far: 37736.0
If we subtract 4890 from 5352, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 9:
815 goes into 4620 5 times with a remainder of 545.
The next digit of our result is 5. 
Result so far: 37736.5
If we subtract 4075 from 4620, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 10:
The number 815 fits into 5450 6 times, leaving a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 37736.56
Subtracting 4890 from 5450 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
When dividing 5600 by 815, we get 6 with a remainder of 710.
Write down 6 as next digit of the result. 
Result so far: 37736.566
If we take 4890 away from 5600, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

After the division, we end up with 37736.566 and a remainder of 0.071.
