We look at the division of 556135 by 53 
The aim is to understand the frequency of 53 in 556135.

Moving on to step 1:
The number 53 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 53

Step 2:
When dividing 55 by 53, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 53 from 55, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 53

Advancing to step 3:
When dividing 26 by 53, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 26, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 53

Advancing to step 4:
The number 53 fits into 261 4 times, leaving a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 49 after subtracting 212 from 261.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 53

Going ahead to step 5:
53 can be fit into 493 9 times, resulting in a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 1049.0
Subtracting 477 from 493 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 53

On to step 6:
165 divided by 53 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 10493.0
The remainder is 6 after subtracting 159 from 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 53, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 10493.1
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.

Going ahead to step 8:
53 goes into 70 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 10493.11
The remainder is 17 after subtracting 53 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 10493.11, with a leftover of 0.017.
