Moving on to step 1:
515 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 515

On to step 2:
The number 515 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 515

Step 3:
515 goes into 215 0 times with a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 215 and we're left with 215.
Grab the next digit (3) from the dividend, add it to 215, then carry on: 2153 / 515

Let's proceed to step 4:
When dividing 2153 by 515, we get 4 with a remainder of 93.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2060 from 2153 to get 93.
Bring next digit (8) of the dividend behind the 93 and repeat the process: 938 / 515

Going ahead to step 5:
The number 515 fits into 938 1 times, leaving a remainder of 423.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 515 from 938 to get 423.
Take the next digit (5) from the dividend and append it to 423, then repeat: 4235 / 515

Let's proceed to step 6:
4235 divided by 515 is 8 with a remainder of 115.
Write down 8 as next digit of the result. 
Result so far: 418.0
The remainder is 115 after subtracting 4120 from 4235.
Bring next digit (8) of the dividend behind the 115 and repeat the process: 1158 / 515

Step 7:
The number 515 fits into 1158 2 times, leaving a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 4182.0
The remainder is 128 after subtracting 1030 from 1158.
Bring next digit (1) of the dividend behind the 128 and repeat the process: 1281 / 515

Moving on to step 8:
515 can be fit into 1281 2 times, resulting in a remainder of 251.
Record the quotient 2 as the next digit in the result. 
Result so far: 41822.0
Subtract 1030 from 1281 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 9:
2510 divided by 515 is 4 with a remainder of 450.
Use 4 as the next digit of our solution. 
Result so far: 41822.4
If we take 2060 away from 2510, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
515 can be fit into 4500 8 times, resulting in a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 41822.48
If we take 4120 away from 4500, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
515 goes into 3800 7 times with a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 41822.487
The remainder is 195 after subtracting 3605 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 12:
515 goes into 1950 3 times with a remainder of 405.
Put 3 as the next digit of the answer. 
Result so far: 41822.4873
The remainder is 405 after subtracting 1545 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 13:
If we divide 4050 by 515, we get 7 and a remainder of 445.
The number 7 becomes the next digit in our result. 
Result so far: 41822.48737
Subtracting 3605 from 4050 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 14:
When dividing 4450 by 515, we get 8 with a remainder of 330.
Put 8 as the next digit of the answer. 
Result so far: 41822.487378
If we subtract 4120 from 4450, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 15:
515 can be fit into 3300 6 times, resulting in a remainder of 210.
The next digit of our result is 6. 
Result so far: 41822.4873786
If we subtract 3090 from 3300, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 16:
515 can be fit into 2100 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 41822.48737864
Subtract 2060 from 2100 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 41822.48737864 and a remainder of 4e-08.
