983533 divided by 53 
The aim is to understand the frequency of 53 in 983533.

On to step 1:
When dividing 9 by 53, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 53

On to step 2:
The number 53 fits into 98 1 times, leaving a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 53 from 98 and we're left with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 53

Going ahead to step 3:
If we divide 453 by 53, we get 8 and a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 424 from 453, we get 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 53

Going ahead to step 4:
295 divided by 53 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtracting 265 from 295 leaves us with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 53

Moving on to step 5:
53 can be fit into 303 5 times, resulting in a remainder of 38.
The next digit of our result is 5. 
Result so far: 1855.0
Subtract 265 from 303 to get 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 53

Let's proceed to step 6:
When dividing 383 by 53, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 18557.0
Subtract 371 from 383 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 53 fits into 120 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 18557.2
If we subtract 106 from 120, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 53, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 18557.22
If we subtract 106 from 140, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 18557.22 with a remaining 0.034.
