We look at the division of 20809190 by 501 
Let's see how many times 501 fits into 20809190.

Moving on to step 1:
501 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 501

Moving on to step 2:
20 divided by 501 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 501

Step 3:
208 divided by 501 is 0 with a remainder of 208.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 208 to get 208.
Grab the next digit (0) from the dividend, add it to 208, then carry on: 2080 / 501

Let's proceed to step 4:
2080 divided by 501 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2004 from 2080, we get 76.
Bring next digit (9) of the dividend behind the 76 and repeat the process: 769 / 501

Going ahead to step 5:
If we divide 769 by 501, we get 1 and a remainder of 268.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 501 from 769 and we're left with 268.
Grab the next digit (1) from the dividend, add it to 268, then carry on: 2681 / 501

Going ahead to step 6:
The number 501 fits into 2681 5 times, leaving a remainder of 176.
The next digit of our result is 5. 
Result so far: 415.0
Subtract 2505 from 2681 to get 176.
Fetch the next digit (9) from the dividend, attach it to 176 and continue: 1769 / 501

Advancing to step 7:
The number 501 fits into 1769 3 times, leaving a remainder of 266.
Write down 3 as next digit of the result. 
Result so far: 4153.0
If we subtract 1503 from 1769, we get 266.
Bring next digit (0) of the dividend behind the 266 and repeat the process: 2660 / 501

Let's proceed to step 8:
If we divide 2660 by 501, we get 5 and a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 41535.0
Subtracting 2505 from 2660 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
501 can be fit into 1550 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 41535.3
Subtracting 1503 from 1550 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
470 divided by 501 is 0 with a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 41535.3
Deduct 0 from 470 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
If we divide 4700 by 501, we get 9 and a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 41535.309
If we take 4509 away from 4700, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 12:
If we divide 1910 by 501, we get 3 and a remainder of 407.
Use 3 as the next digit of our solution. 
Result so far: 41535.3093
The remainder is 407 after subtracting 1503 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 13:
If we divide 4070 by 501, we get 8 and a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 41535.30938
Subtracting 4008 from 4070 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
620 divided by 501 is 1 with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 41535.309381
If we subtract 501 from 620, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 15:
501 can be fit into 1190 2 times, resulting in a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 41535.3093812
If we take 1002 away from 1190, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 16:
The number 501 fits into 1880 3 times, leaving a remainder of 377.
The next digit of our result is 3. 
Result so far: 41535.30938123
Subtracting 1503 from 1880 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

After the division, we end up with 41535.30938123 and a remainder of 3.77e-07.
