We're dividing 20246530 by 515 
Our goal is to divide 20246530 by 515.

Step 1:
When dividing 2 by 515, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 515

Advancing to step 2:
If we divide 20 by 515, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 515

Going ahead to step 3:
202 divided by 515 is 0 with a remainder of 202.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 202, we get 202.
Grab the next digit (4) from the dividend, add it to 202, then carry on: 2024 / 515

Going ahead to step 4:
515 can be fit into 2024 3 times, resulting in a remainder of 479.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1545 from 2024 and we're left with 479.
Grab the next digit (6) from the dividend, add it to 479, then carry on: 4796 / 515

On to step 5:
4796 divided by 515 is 9 with a remainder of 161.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 4635 from 4796 leaves us with 161.
Grab the next digit (5) from the dividend, add it to 161, then carry on: 1615 / 515

Let's proceed to step 6:
The number 515 fits into 1615 3 times, leaving a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 393.0
If we subtract 1545 from 1615, we get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 515

Moving on to step 7:
515 goes into 703 1 times with a remainder of 188.
Record the quotient 1 as the next digit in the result. 
Result so far: 3931.0
The remainder is 188 after subtracting 515 from 703.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 515

Moving on to step 8:
1880 divided by 515 is 3 with a remainder of 335.
The number 3 becomes the next digit in our result. 
Result so far: 39313.0
If we subtract 1545 from 1880, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 9:
515 goes into 3350 6 times with a remainder of 260.
The next digit of our result is 6. 
Result so far: 39313.6
Subtract 3090 from 3350 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
2600 divided by 515 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 39313.65
Deduct 2575 from 2600 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
When dividing 250 by 515, we get 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 39313.65
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
515 can be fit into 2500 4 times, resulting in a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 39313.6504
The remainder is 440 after subtracting 2060 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
The number 515 fits into 4400 8 times, leaving a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 39313.65048
Subtracting 4120 from 4400 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 14:
If we divide 2800 by 515, we get 5 and a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 39313.650485
The remainder is 225 after subtracting 2575 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 15:
515 can be fit into 2250 4 times, resulting in a remainder of 190.
Record the quotient 4 as the next digit in the result. 
Result so far: 39313.6504854
Subtract 2060 from 2250 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 16:
When dividing 1900 by 515, we get 3 with a remainder of 355.
The next digit of our result is 3. 
Result so far: 39313.65048543
Subtracting 1545 from 1900 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The final result is 39313.65048543 with a remainder of 3.55e-07.
