We're dividing 53224885 by 810 
The aim is to understand the frequency of 810 in 53224885.

Let's proceed to step 1:
The number 810 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 810

Advancing to step 2:
The number 810 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 810

Step 3:
The number 810 fits into 532 0 times, leaving a remainder of 532.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 532 and we're left with 532.
Fetch the next digit (2) from the dividend, attach it to 532 and continue: 5322 / 810

Step 4:
The number 810 fits into 5322 6 times, leaving a remainder of 462.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4860 from 5322 and we're left with 462.
Append the next digit (4) from the dividend to 462 and continue with: 4624 / 810

Advancing to step 5:
810 goes into 4624 5 times with a remainder of 574.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 4050 from 4624 and we're left with 574.
Bring next digit (8) of the dividend behind the 574 and repeat the process: 5748 / 810

Going ahead to step 6:
If we divide 5748 by 810, we get 7 and a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 657.0
If we take 5670 away from 5748, we end up with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 810

Step 7:
If we divide 788 by 810, we get 0 and a remainder of 788.
The next digit of our result is 0. 
Result so far: 6570.0
If we subtract 0 from 788, we get 788.
Take the next digit (5) from the dividend and append it to 788, then repeat: 7885 / 810

Advancing to step 8:
7885 divided by 810 is 9 with a remainder of 595.
The number 9 becomes the next digit in our result. 
Result so far: 65709.0
Subtracting 7290 from 7885 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 9:
810 can be fit into 5950 7 times, resulting in a remainder of 280.
Use 7 as the next digit of our solution. 
Result so far: 65709.7
The remainder is 280 after subtracting 5670 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
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: 65709.73
Deduct 2430 from 2800 and we're left 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.

On to step 11:
If we divide 3700 by 810, we get 4 and a remainder of 460.
The number 4 becomes the next digit in our result. 
Result so far: 65709.734
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.

Step 12:
4600 divided by 810 is 5 with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 65709.7345
If we take 4050 away from 4600, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 13:
810 can be fit into 5500 6 times, resulting in a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 65709.73456
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.

Let's proceed to step 14:
If we divide 6400 by 810, we get 7 and a remainder of 730.
Put 7 as the next digit of the answer. 
Result so far: 65709.734567
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.

Let's proceed to step 15:
The number 810 fits into 7300 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 65709.7345679
The remainder is 10 after subtracting 7290 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
The number 810 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 65709.7345679
Subtracting 0 from 100 leaves us 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.

The quotient of the division is 65709.7345679, and the remainder is 1e-07.
