We look at the division of 265635 by 53 
The aim is to understand the frequency of 53 in 265635.

Going ahead to step 1:
When dividing 2 by 53, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 53

Moving on to step 2:
If we divide 26 by 53, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 53

Let's proceed to step 3:
53 goes into 265 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 265 from 265, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 53

Advancing to step 4:
6 divided by 53 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 53

On to step 5:
If we divide 63 by 53, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 501.0
Deduct 53 from 63 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 53

Let's proceed to step 6:
53 can be fit into 105 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 5011.0
The remainder is 52 after subtracting 53 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
53 can be fit into 520 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 5011.9
Subtract 477 from 520 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
430 divided by 53 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 5011.98
Subtract 424 from 430 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
53 can be fit into 60 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 5011.981
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.

Advancing to step 10:
The number 53 fits into 70 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 5011.9811
Subtract 53 from 70 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 5011.9811 and a remainder of 0.00017.
