Let's divide 515023 by 53
The aim is to understand the frequency of 53 in 515023.

Let's proceed to step 1:
When dividing 5 by 53, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 53

On to step 2:
53 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 53

Step 3:
515 divided by 53 is 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 477 from 515 leaves us with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 53

Going ahead to step 4:
53 goes into 380 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 371 from 380 and we're left with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 53

Advancing to step 5:
53 can be fit into 92 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 971.0
The remainder is 39 after subtracting 53 from 92.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 53

Advancing to step 6:
53 goes into 393 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 9717.0
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:
If we divide 220 by 53, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9717.4
Subtracting 212 from 220 leaves us 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.

Step 8:
If we divide 80 by 53, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 9717.41
Deduct 53 from 80 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
270 divided by 53 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9717.415
Deduct 265 from 270 and we're left 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:
If we divide 50 by 53, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9717.415
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
When dividing 500 by 53, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 9717.41509
Subtracting 477 from 500 leaves us 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.

Step 12:
The number 53 fits into 230 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 9717.415094
Deduct 212 from 230 and we're left with 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:
If we divide 180 by 53, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 9717.4150943
Deduct 159 from 180 and we're left 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.

Let's proceed to step 14:
53 can be fit into 210 3 times, resulting in a remainder of 51.
The next digit of our result is 3. 
Result so far: 9717.41509433
The remainder is 51 after subtracting 159 from 210.
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 result is 9717.41509433 with a remainder of 5.1e-08.
