Let's divide 20486923 by 810
We're looking to find how many times 810 goes into 20486923.

Moving on 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.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 810

Step 2:
810 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 810

Step 3:
When dividing 204 by 810, we get 0 with a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Bring next digit (8) of the dividend behind the 204 and repeat the process: 2048 / 810

Step 4:
If we divide 2048 by 810, we get 2 and a remainder of 428.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1620 away from 2048, we end up with 428.
Append the next digit (6) from the dividend to 428 and continue with: 4286 / 810

Advancing to step 5:
810 goes into 4286 5 times with a remainder of 236.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 4050 from 4286, we get 236.
Take the next digit (9) from the dividend and append it to 236, then repeat: 2369 / 810

Moving on to step 6:
The number 810 fits into 2369 2 times, leaving a remainder of 749.
Put 2 as the next digit of the answer. 
Result so far: 252.0
Subtracting 1620 from 2369 leaves us with 749.
Take the next digit (2) from the dividend and append it to 749, then repeat: 7492 / 810

Moving on to step 7:
When dividing 7492 by 810, we get 9 with a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 2529.0
Deduct 7290 from 7492 and we're left with 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 810

Advancing to step 8:
810 goes into 2023 2 times with a remainder of 403.
Record the quotient 2 as the next digit in the result. 
Result so far: 25292.0
The remainder is 403 after subtracting 1620 from 2023.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 9:
810 can be fit into 4030 4 times, resulting in a remainder of 790.
The number 4 becomes the next digit in our result. 
Result so far: 25292.4
If we subtract 3240 from 4030, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
The number 810 fits into 7900 9 times, leaving a remainder of 610.
Write down 9 as next digit of the result. 
Result so far: 25292.49
If we subtract 7290 from 7900, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 11:
If we divide 6100 by 810, we get 7 and a remainder of 430.
Put 7 as the next digit of the answer. 
Result so far: 25292.497
If we take 5670 away from 6100, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 12:
If we divide 4300 by 810, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 25292.4975
If we take 4050 away from 4300, 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 13:
810 can be fit into 2500 3 times, resulting in a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 25292.49753
If we subtract 2430 from 2500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
When dividing 700 by 810, we get 0 with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 25292.49753
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 15:
The number 810 fits into 7000 8 times, leaving a remainder of 520.
Record the quotient 8 as the next digit in the result. 
Result so far: 25292.4975308
If we subtract 6480 from 7000, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
5200 divided by 810 is 6 with a remainder of 340.
The next digit of our result is 6. 
Result so far: 25292.49753086
Subtracting 4860 from 5200 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

In conclusion, the division gives 25292.49753086 with a balance of 3.4e-07.
