We look at the division of 204805 by 53 
The aim is to understand the frequency of 53 in 204805.

Step 1:
When dividing 2 by 53, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 53

Let's proceed to step 2:
The number 53 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 53

Going ahead to step 3:
The number 53 fits into 204 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 159 from 204 to get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 53

Going ahead to step 4:
If we divide 458 by 53, we get 8 and a remainder of 34.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 424 from 458 to get 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 53

Moving on to step 5:
53 can be fit into 340 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 386.0
Deduct 318 from 340 and we're left with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 53

Advancing to step 6:
53 goes into 225 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 3864.0
The remainder is 13 after subtracting 212 from 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 53, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3864.2
If we take 106 away from 130, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
240 divided by 53 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 3864.24
If we subtract 212 from 240, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 53, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 3864.245
If we take 265 away from 280, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
The number 53 fits into 150 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 3864.2452
If we subtract 106 from 150, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
If we divide 440 by 53, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 3864.24528
The remainder is 16 after subtracting 424 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 53, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3864.245283
If we subtract 159 from 160, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
53 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3864.245283
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
The number 53 fits into 100 1 times, leaving a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 3864.24528301
Deduct 53 from 100 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 3864.24528301 and a remainder of 4.7e-08.
