805921 divided by 53 
The aim is to understand the frequency of 53 in 805921.

Going ahead to step 1:
8 divided by 53 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 53

On to step 2:
If we divide 80 by 53, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 53 from 80 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 53

Going ahead to step 3:
53 can be fit into 275 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 265 from 275 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 53

Let's proceed to step 4:
The number 53 fits into 109 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 106 from 109 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 53

On to step 5:
The number 53 fits into 32 0 times, leaving a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 1520.0
If we subtract 0 from 32, we get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 53

Advancing to step 6:
The number 53 fits into 321 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 15206.0
Subtract 318 from 321 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
53 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 15206.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 53 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15206.05
The remainder is 35 after subtracting 265 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
If we divide 350 by 53, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 15206.056
If we subtract 318 from 350, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
When dividing 320 by 53, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 15206.0566
The remainder is 2 after subtracting 318 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 15206.0566 and a remainder of 2e-05.
