We look at the division of 724983 by 53 
The aim is to understand the frequency of 53 in 724983.

Advancing to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 53

On to step 2:
If we divide 72 by 53, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 53 from 72, we get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 53

Step 3:
If we divide 194 by 53, we get 3 and a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 159 from 194 and we're left with 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 53

Step 4:
53 can be fit into 359 6 times, resulting in a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtract 318 from 359 to get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 53

Step 5:
When dividing 418 by 53, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 1367.0
The remainder is 47 after subtracting 371 from 418.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 53

Moving on to step 6:
53 goes into 473 8 times with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 13678.0
Deduct 424 from 473 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
The number 53 fits into 490 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 13678.9
Subtract 477 from 490 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
The number 53 fits into 130 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 13678.92
Deduct 106 from 130 and we're left 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.

Moving on to step 9:
53 can be fit into 240 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 13678.924
The remainder is 28 after subtracting 212 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 53 fits into 280 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 13678.9245
If we subtract 265 from 280, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 53 fits into 150 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 13678.92452
If we take 106 away from 150, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
440 divided by 53 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 13678.924528
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.

Advancing to step 13:
53 can be fit into 160 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13678.9245283
Subtract 159 from 160 to 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.

Moving on to step 14:
53 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13678.9245283
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 13678.9245283 with a remaining 1e-08.
