We're dividing 39682817 by 810 
We want to figure out the number of times 39682817 can be divided by 810.

On to step 1:
The number 810 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 810

Moving on to step 2:
The number 810 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 810

On to step 3:
396 divided by 810 is 0 with a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 396 to get 396.
Take the next digit (8) from the dividend and append it to 396, then repeat: 3968 / 810

Advancing to step 4:
The number 810 fits into 3968 4 times, leaving a remainder of 728.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3240 from 3968 leaves us with 728.
Include the next digit (2) from the dividend after 728, then repeat: 7282 / 810

Step 5:
7282 divided by 810 is 8 with a remainder of 802.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 6480 from 7282 to get 802.
Append the next digit (8) from the dividend to 802 and continue with: 8028 / 810

Moving on to step 6:
If we divide 8028 by 810, we get 9 and a remainder of 738.
The number 9 becomes the next digit in our result. 
Result so far: 489.0
If we subtract 7290 from 8028, we get 738.
Fetch the next digit (1) from the dividend, attach it to 738 and continue: 7381 / 810

On to step 7:
If we divide 7381 by 810, we get 9 and a remainder of 91.
Record the quotient 9 as the next digit in the result. 
Result so far: 4899.0
If we take 7290 away from 7381, we end up with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 810

Moving on to step 8:
When dividing 917 by 810, we get 1 with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 48991.0
If we subtract 810 from 917, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
The number 810 fits into 1070 1 times, leaving a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 48991.1
Deduct 810 from 1070 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
2600 divided by 810 is 3 with a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 48991.13
Subtract 2430 from 2600 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
If we divide 1700 by 810, we get 2 and a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 48991.132
The remainder is 80 after subtracting 1620 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
The number 810 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 48991.132
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 13:
The number 810 fits into 8000 9 times, leaving a remainder of 710.
Write down 9 as next digit of the result. 
Result so far: 48991.13209
Subtracting 7290 from 8000 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 14:
If we divide 7100 by 810, we get 8 and a remainder of 620.
Use 8 as the next digit of our solution. 
Result so far: 48991.132098
Subtracting 6480 from 7100 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 15:
6200 divided by 810 is 7 with a remainder of 530.
Put 7 as the next digit of the answer. 
Result so far: 48991.1320987
If we subtract 5670 from 6200, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 16:
810 goes into 5300 6 times with a remainder of 440.
Put 6 as the next digit of the answer. 
Result so far: 48991.13209876
Subtracting 4860 from 5300 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

After the division, we end up with 48991.13209876 and a remainder of 4.4e-07.
