We're dividing 20720350 by 810 
We're looking to find how many times 810 goes into 20720350.

Going ahead to step 1:
If we divide 2 by 810, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
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 / 810

On to step 2:
The number 810 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 810

Let's proceed to step 3:
810 can be fit into 207 0 times, resulting in a remainder of 207.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 207 and we're left with 207.
Take the next digit (2) from the dividend and append it to 207, then repeat: 2072 / 810

On to step 4:
If we divide 2072 by 810, we get 2 and a remainder of 452.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1620 away from 2072, we end up with 452.
Bring next digit (0) of the dividend behind the 452 and repeat the process: 4520 / 810

Going ahead to step 5:
4520 divided by 810 is 5 with a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 470 after subtracting 4050 from 4520.
Include the next digit (3) from the dividend after 470, then repeat: 4703 / 810

On to step 6:
810 goes into 4703 5 times with a remainder of 653.
Write down 5 as next digit of the result. 
Result so far: 255.0
If we take 4050 away from 4703, we end up with 653.
Include the next digit (5) from the dividend after 653, then repeat: 6535 / 810

Let's proceed to step 7:
If we divide 6535 by 810, we get 8 and a remainder of 55.
The next digit of our result is 8. 
Result so far: 2558.0
If we subtract 6480 from 6535, we get 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 810

Let's proceed to step 8:
The number 810 fits into 550 0 times, leaving a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 25580.0
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 9:
If we divide 5500 by 810, we get 6 and a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 25580.6
If we take 4860 away from 5500, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 10:
When dividing 6400 by 810, we get 7 with a remainder of 730.
The next digit of our result is 7. 
Result so far: 25580.67
Deduct 5670 from 6400 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 11:
When dividing 7300 by 810, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 25580.679
Subtract 7290 from 7300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
The number 810 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 25580.679
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
810 goes into 1000 1 times with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 25580.67901
If we subtract 810 from 1000, we 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.

Moving on to step 14:
810 goes into 1900 2 times with a remainder of 280.
The next digit of our result is 2. 
Result so far: 25580.679012
If we subtract 1620 from 1900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
If we divide 2800 by 810, we get 3 and a remainder of 370.
Record the quotient 3 as the next digit in the result. 
Result so far: 25580.6790123
If we take 2430 away from 2800, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 16:
If we divide 3700 by 810, we get 4 and a remainder of 460.
Write down 4 as next digit of the result. 
Result so far: 25580.67901234
Deduct 3240 from 3700 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The quotient of the division is 25580.67901234, and the remainder is 4.6e-07.
