We look at the division of 653883 by 53 
The aim is to understand the frequency of 53 in 653883.

Moving on to step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 53

On to step 2:
When dividing 65 by 53, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 53 away from 65, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 53

Advancing to step 3:
53 can be fit into 123 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 17 after subtracting 106 from 123.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 53

Going ahead to step 4:
If we divide 178 by 53, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 159 from 178 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 53

Advancing to step 5:
The number 53 fits into 198 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1233.0
If we subtract 159 from 198, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 53

On to step 6:
The number 53 fits into 393 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 12337.0
If we subtract 371 from 393, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
53 goes into 220 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 12337.4
Deduct 212 from 220 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 53 fits into 80 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 12337.41
Subtract 53 from 80 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
53 can be fit into 270 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12337.415
Subtracting 265 from 270 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 53 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 12337.415
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
The number 53 fits into 500 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 12337.41509
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 53, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 12337.415094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
When dividing 180 by 53, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 12337.4150943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
53 goes into 210 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 12337.41509433
If we take 159 away from 210, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 12337.41509433, with a leftover of 5.1e-08.
