We look at the division of 533500 by 53 
The aim is to understand the frequency of 53 in 533500.

Step 1:
5 divided by 53 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 53

On to step 2:
53 can be fit into 53 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 53 from 53 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 53

Step 3:
When dividing 3 by 53, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 53

Let's proceed to step 4:
53 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 35, we end up with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 53

Advancing to step 5:
If we divide 350 by 53, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 1006.0
If we subtract 318 from 350, we get 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 53

Going ahead to step 6:
If we divide 320 by 53, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 10066.0
Deduct 318 from 320 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 53 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 10066.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
53 goes into 200 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 10066.03
Deduct 159 from 200 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
The number 53 fits into 410 7 times, leaving a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 10066.037
If we subtract 371 from 410, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 10:
53 goes into 390 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 10066.0377
Subtract 371 from 390 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 10066.0377 and a remainder of 0.00019.
