We look at the division of 451756 by 810 
The aim is to understand the frequency of 810 in 451756.

Going ahead to step 1:
4 divided by 810 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 810

Let's proceed to step 2:
45 divided by 810 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 810

Let's proceed to step 3:
810 can be fit into 451 0 times, resulting in a remainder of 451.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 451 to get 451.
Include the next digit (7) from the dividend after 451, then repeat: 4517 / 810

Let's proceed to step 4:
If we divide 4517 by 810, we get 5 and a remainder of 467.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 467 after subtracting 4050 from 4517.
Fetch the next digit (5) from the dividend, attach it to 467 and continue: 4675 / 810

Going ahead to step 5:
When dividing 4675 by 810, we get 5 with a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtracting 4050 from 4675 leaves us with 625.
Fetch the next digit (6) from the dividend, attach it to 625 and continue: 6256 / 810

Advancing to step 6:
810 can be fit into 6256 7 times, resulting in a remainder of 586.
The number 7 becomes the next digit in our result. 
Result so far: 557.0
If we take 5670 away from 6256, we end up with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 7:
If we divide 5860 by 810, we get 7 and a remainder of 190.
Use 7 as the next digit of our solution. 
Result so far: 557.7
Subtract 5670 from 5860 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 8:
If we divide 1900 by 810, we get 2 and a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 557.72
If we subtract 1620 from 1900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 9:
810 goes into 2800 3 times with a remainder of 370.
Use 3 as the next digit of our solution. 
Result so far: 557.723
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.

Going ahead to step 10:
The number 810 fits into 3700 4 times, leaving a remainder of 460.
Use 4 as the next digit of our solution. 
Result so far: 557.7234
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.

Moving on to step 11:
4600 divided by 810 is 5 with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 557.72345
The remainder is 550 after subtracting 4050 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 12:
The number 810 fits into 5500 6 times, leaving a remainder of 640.
Use 6 as the next digit of our solution. 
Result so far: 557.723456
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.

Step 13:
The number 810 fits into 6400 7 times, leaving a remainder of 730.
Record the quotient 7 as the next digit in the result. 
Result so far: 557.7234567
If we take 5670 away from 6400, we end up 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.

On to step 14:
7300 divided by 810 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 557.72345679
If we take 7290 away from 7300, we end up 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.

The quotient of the division is 557.72345679, and the remainder is 1e-08.
