We look at the division of 20853924 by 515 
Our goal is to divide 20853924 by 515.

Moving on to step 1:
If we divide 2 by 515, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 515

Advancing to step 2:
The number 515 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 515

Let's proceed to step 3:
515 goes into 208 0 times with a remainder of 208.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 208 after subtracting 0 from 208.
Include the next digit (5) from the dividend after 208, then repeat: 2085 / 515

Moving on to step 4:
The number 515 fits into 2085 4 times, leaving a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 2060 from 2085 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 515

Let's proceed to step 5:
515 goes into 253 0 times with a remainder of 253.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 253, we get 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 515

Step 6:
515 goes into 2539 4 times with a remainder of 479.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
The remainder is 479 after subtracting 2060 from 2539.
Take the next digit (2) from the dividend and append it to 479, then repeat: 4792 / 515

Let's proceed to step 7:
The number 515 fits into 4792 9 times, leaving a remainder of 157.
Use 9 as the next digit of our solution. 
Result so far: 4049.0
Subtracting 4635 from 4792 leaves us with 157.
Include the next digit (4) from the dividend after 157, then repeat: 1574 / 515

Moving on to step 8:
515 goes into 1574 3 times with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 40493.0
If we take 1545 away from 1574, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
515 goes into 290 0 times with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 40493.0
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
If we divide 2900 by 515, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 40493.05
If we subtract 2575 from 2900, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 11:
When dividing 3250 by 515, we get 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 40493.056
If we take 3090 away from 3250, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
515 goes into 1600 3 times with a remainder of 55.
The next digit of our result is 3. 
Result so far: 40493.0563
If we take 1545 away from 1600, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
If we divide 550 by 515, we get 1 and a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 40493.05631
If we subtract 515 from 550, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
The number 515 fits into 350 0 times, leaving a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 40493.05631
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 15:
The number 515 fits into 3500 6 times, leaving a remainder of 410.
Record the quotient 6 as the next digit in the result. 
Result so far: 40493.0563106
If we subtract 3090 from 3500, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 16:
515 can be fit into 4100 7 times, resulting in a remainder of 495.
The next digit of our result is 7. 
Result so far: 40493.05631067
If we subtract 3605 from 4100, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Our division results in 40493.05631067 with a remaining 4.95e-07.
