We're dividing 763636 by 53 
The aim is to understand the frequency of 53 in 763636.

Step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 53

Advancing to step 2:
When dividing 76 by 53, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 53 from 76, we get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 53

Going ahead to step 3:
233 divided by 53 is 4 with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 212 from 233 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 53

On to step 4:
The number 53 fits into 216 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we take 212 away from 216, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 53

Step 5:
The number 53 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 1440.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 53

On to step 6:
53 goes into 436 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 14408.0
Deduct 424 from 436 and we're left with 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:
53 can be fit into 120 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 14408.2
Subtract 106 from 120 to 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.

Moving on to step 8:
The number 53 fits into 140 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 14408.22
Deduct 106 from 140 and we're left with 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 14408.22 with a remaining 0.034.
