Let's divide 993709 by 53
The aim is to understand the frequency of 53 in 993709.

Going ahead to step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 53

On to step 2:
The number 53 fits into 99 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 53 from 99, we get 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 53

Let's proceed to step 3:
The number 53 fits into 463 8 times, leaving a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 424 from 463 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 53

Step 4:
If we divide 397 by 53, we get 7 and a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
If we subtract 371 from 397, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 53

Advancing to step 5:
260 divided by 53 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 1874.0
Subtracting 212 from 260 leaves us with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 53

Moving on to step 6:
489 divided by 53 is 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 18749.0
Subtract 477 from 489 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.

Let's proceed to step 7:
The number 53 fits into 120 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 18749.2
Deduct 106 from 120 and we're left with 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.
Use 2 as the next digit of our solution. 
Result so far: 18749.22
The remainder is 34 after subtracting 106 from 140.
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 18749.22 with a remaining 0.034.
