We're dividing 2752763 by 810 
The aim is to understand the frequency of 810 in 2752763.

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
Subtracting 0 from 2 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 810

Let's proceed to step 2:
810 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 810

Advancing to step 3:
When dividing 275 by 810, we get 0 with a remainder of 275.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 275 leaves us with 275.
Bring next digit (2) of the dividend behind the 275 and repeat the process: 2752 / 810

Advancing to step 4:
If we divide 2752 by 810, we get 3 and a remainder of 322.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2430 from 2752 leaves us with 322.
Append the next digit (7) from the dividend to 322 and continue with: 3227 / 810

Going ahead to step 5:
If we divide 3227 by 810, we get 3 and a remainder of 797.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 2430 from 3227 and we're left with 797.
Fetch the next digit (6) from the dividend, attach it to 797 and continue: 7976 / 810

On to step 6:
7976 divided by 810 is 9 with a remainder of 686.
Use 9 as the next digit of our solution. 
Result so far: 339.0
The remainder is 686 after subtracting 7290 from 7976.
Take the next digit (3) from the dividend and append it to 686, then repeat: 6863 / 810

Step 7:
The number 810 fits into 6863 8 times, leaving a remainder of 383.
The number 8 becomes the next digit in our result. 
Result so far: 3398.0
The remainder is 383 after subtracting 6480 from 6863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 8:
When dividing 3830 by 810, we get 4 with a remainder of 590.
The number 4 becomes the next digit in our result. 
Result so far: 3398.4
The remainder is 590 after subtracting 3240 from 3830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 9:
810 can be fit into 5900 7 times, resulting in a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 3398.47
Subtracting 5670 from 5900 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
810 goes into 2300 2 times with a remainder of 680.
Use 2 as the next digit of our solution. 
Result so far: 3398.472
If we subtract 1620 from 2300, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
810 can be fit into 6800 8 times, resulting in a remainder of 320.
Write down 8 as next digit of the result. 
Result so far: 3398.4728
Deduct 6480 from 6800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
The number 810 fits into 3200 3 times, leaving a remainder of 770.
The number 3 becomes the next digit in our result. 
Result so far: 3398.47283
If we subtract 2430 from 3200, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 13:
The number 810 fits into 7700 9 times, leaving a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 3398.472839
If we subtract 7290 from 7700, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 14:
When dividing 4100 by 810, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3398.4728395
Subtracting 4050 from 4100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 15:
810 can be fit into 500 0 times, resulting in a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 3398.4728395
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 3398.4728395 and a remainder of 5e-07.
