We look at the division of 23982040 by 810 
We want to figure out the number of times 23982040 can be divided by 810.

Going ahead to step 1:
When dividing 2 by 810, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 810

Let's proceed to step 2:
When dividing 23 by 810, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 810

Step 3:
239 divided by 810 is 0 with a remainder of 239.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 239 and we're left with 239.
Take the next digit (8) from the dividend and append it to 239, then repeat: 2398 / 810

Let's proceed to step 4:
810 can be fit into 2398 2 times, resulting in a remainder of 778.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1620 from 2398 leaves us with 778.
Grab the next digit (2) from the dividend, add it to 778, then carry on: 7782 / 810

Going ahead to step 5:
810 can be fit into 7782 9 times, resulting in a remainder of 492.
Write down 9 as next digit of the result. 
Result so far: 29.0
The remainder is 492 after subtracting 7290 from 7782.
Append the next digit (0) from the dividend to 492 and continue with: 4920 / 810

Step 6:
810 goes into 4920 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 296.0
The remainder is 60 after subtracting 4860 from 4920.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 810

Step 7:
810 goes into 604 0 times with a remainder of 604.
The number 0 becomes the next digit in our result. 
Result so far: 2960.0
If we subtract 0 from 604, we get 604.
Include the next digit (0) from the dividend after 604, then repeat: 6040 / 810

On to step 8:
810 goes into 6040 7 times with a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 29607.0
If we subtract 5670 from 6040, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 9:
The number 810 fits into 3700 4 times, leaving a remainder of 460.
Record the quotient 4 as the next digit in the result. 
Result so far: 29607.4
If we subtract 3240 from 3700, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
When dividing 4600 by 810, we get 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 29607.45
Subtract 4050 from 4600 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
When dividing 5500 by 810, we get 6 with a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 29607.456
If we subtract 4860 from 5500, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 12:
810 goes into 6400 7 times with a remainder of 730.
Write down 7 as next digit of the result. 
Result so far: 29607.4567
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.

Moving on to step 13:
7300 divided by 810 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 29607.45679
Subtracting 7290 from 7300 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
810 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 29607.45679
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.

Going ahead to step 15:
1000 divided by 810 is 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 29607.4567901
Deduct 810 from 1000 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
When dividing 1900 by 810, we get 2 with a remainder of 280.
The number 2 becomes the next digit in our result. 
Result so far: 29607.45679012
The remainder is 280 after subtracting 1620 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 29607.45679012, with a leftover of 2.8e-07.
