We divide 21395158 by 515
We're looking to find how many times 515 goes into 21395158.

Let's proceed to step 1:
When dividing 2 by 515, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 515

Going ahead to step 2:
21 divided by 515 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 515

Step 3:
213 divided by 515 is 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Fetch the next digit (9) from the dividend, attach it to 213 and continue: 2139 / 515

Moving on to step 4:
515 goes into 2139 4 times with a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 79 after subtracting 2060 from 2139.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 515

Going ahead to step 5:
When dividing 795 by 515, we get 1 with a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 515 from 795, we get 280.
Bring next digit (1) of the dividend behind the 280 and repeat the process: 2801 / 515

Going ahead to step 6:
2801 divided by 515 is 5 with a remainder of 226.
Put 5 as the next digit of the answer. 
Result so far: 415.0
The remainder is 226 after subtracting 2575 from 2801.
Include the next digit (5) from the dividend after 226, then repeat: 2265 / 515

Step 7:
The number 515 fits into 2265 4 times, leaving a remainder of 205.
The number 4 becomes the next digit in our result. 
Result so far: 4154.0
If we take 2060 away from 2265, we end up with 205.
Take the next digit (8) from the dividend and append it to 205, then repeat: 2058 / 515

Let's proceed to step 8:
If we divide 2058 by 515, we get 3 and a remainder of 513.
Put 3 as the next digit of the answer. 
Result so far: 41543.0
Deduct 1545 from 2058 and we're left with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 9:
The number 515 fits into 5130 9 times, leaving a remainder of 495.
Record the quotient 9 as the next digit in the result. 
Result so far: 41543.9
Deduct 4635 from 5130 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 10:
If we divide 4950 by 515, we get 9 and a remainder of 315.
Use 9 as the next digit of our solution. 
Result so far: 41543.99
Subtract 4635 from 4950 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

In conclusion, the division gives 41543.99 with a balance of 0.315.
