We look at the division of 840003 by 53 
The aim is to understand the frequency of 53 in 840003.

Moving on to step 1:
If we divide 8 by 53, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 53

Let's proceed to step 2:
The number 53 fits into 84 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 53 away from 84, we end up with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 53

Let's proceed to step 3:
53 can be fit into 310 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 265 from 310 leaves us with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 53

Step 4:
53 goes into 450 8 times with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we take 424 away from 450, we end up with 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 53

On to step 5:
53 can be fit into 260 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 1584.0
The remainder is 48 after subtracting 212 from 260.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 53

Moving on to step 6:
The number 53 fits into 483 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 15849.0
Deduct 477 from 483 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 53, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 15849.1
Subtract 53 from 60 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
The number 53 fits into 70 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 15849.11
If we take 53 away from 70, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 15849.11 with a balance of 0.017.
