804106 ÷ 53 
The aim is to understand the frequency of 53 in 804106.

Let's proceed to step 1:
If we divide 8 by 53, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 53

Let's proceed to step 2:
53 can be fit into 80 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 53 from 80 and we're left with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 53

Step 3:
The number 53 fits into 274 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 9 after subtracting 265 from 274.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 53

Step 4:
If we divide 91 by 53, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 53 from 91 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 53

Going ahead to step 5:
380 divided by 53 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 1517.0
If we take 371 away from 380, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 53

Moving on to step 6:
96 divided by 53 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 15171.0
Deduct 53 from 96 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
53 goes into 430 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 15171.8
Subtract 424 from 430 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 53, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 15171.81
The remainder is 7 after subtracting 53 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
53 goes into 70 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 15171.811
Subtract 53 from 70 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 15171.811 with a remaining 0.0017.
