504511 ÷ 53 
The aim is to understand the frequency of 53 in 504511.

Step 1:
53 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 53

Step 2:
The number 53 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 53

Moving on to step 3:
53 goes into 504 9 times with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 477 from 504, we get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 53

On to step 4:
53 goes into 275 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we take 265 away from 275, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 53

Advancing to step 5:
101 divided by 53 is 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 951.0
If we subtract 53 from 101, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 53

Going ahead to step 6:
The number 53 fits into 481 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9519.0
If we take 477 away from 481, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 53 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9519.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 53 is 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 9519.07
If we take 371 away from 400, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
290 divided by 53 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9519.075
Deduct 265 from 290 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
53 can be fit into 250 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 9519.0754
The remainder is 38 after subtracting 212 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
When dividing 380 by 53, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 9519.07547
Subtract 371 from 380 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
The number 53 fits into 90 1 times, leaving a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 9519.075471
Deduct 53 from 90 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
53 can be fit into 370 6 times, resulting in a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 9519.0754716
Subtract 318 from 370 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
If we divide 520 by 53, we get 9 and a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 9519.07547169
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 9519.07547169 and a remainder of 4.3e-08.
