Let's divide 38452510 by 815
We want to figure out the number of times 38452510 can be divided by 815.

Going ahead to step 1:
3 divided by 815 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 815

Advancing to step 2:
38 divided by 815 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 815

Step 3:
384 divided by 815 is 0 with a remainder of 384.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 384 to get 384.
Include the next digit (5) from the dividend after 384, then repeat: 3845 / 815

Let's proceed to step 4:
The number 815 fits into 3845 4 times, leaving a remainder of 585.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3260 from 3845 and we're left with 585.
Take the next digit (2) from the dividend and append it to 585, then repeat: 5852 / 815

On to step 5:
5852 divided by 815 is 7 with a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 5705 away from 5852, we end up with 147.
Grab the next digit (5) from the dividend, add it to 147, then carry on: 1475 / 815

On to step 6:
The number 815 fits into 1475 1 times, leaving a remainder of 660.
Put 1 as the next digit of the answer. 
Result so far: 471.0
If we take 815 away from 1475, we end up with 660.
Append the next digit (1) from the dividend to 660 and continue with: 6601 / 815

Let's proceed to step 7:
6601 divided by 815 is 8 with a remainder of 81.
Record the quotient 8 as the next digit in the result. 
Result so far: 4718.0
If we take 6520 away from 6601, we end up with 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 815

On to step 8:
The number 815 fits into 810 0 times, leaving a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 47180.0
Deduct 0 from 810 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 9:
The number 815 fits into 8100 9 times, leaving a remainder of 765.
Record the quotient 9 as the next digit in the result. 
Result so far: 47180.9
Subtracting 7335 from 8100 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Advancing to step 10:
815 can be fit into 7650 9 times, resulting in a remainder of 315.
Put 9 as the next digit of the answer. 
Result so far: 47180.99
Subtracting 7335 from 7650 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Our division results in 47180.99 with a remaining 0.315.
