We look at the division of 261165 by 53 
The aim is to understand the frequency of 53 in 261165.

Going ahead to step 1:
53 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 53

Moving on to step 2:
When dividing 26 by 53, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 53

Step 3:
53 goes into 261 4 times with a remainder of 49.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 212 from 261 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 53

Moving on to step 4:
If we divide 491 by 53, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 477 from 491 to get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 53

Step 5:
146 divided by 53 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 492.0
If we take 106 away from 146, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 53

Going ahead to step 6:
If we divide 405 by 53, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 4927.0
Deduct 371 from 405 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.

Advancing to step 7:
53 can be fit into 340 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 4927.6
Deduct 318 from 340 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
When dividing 220 by 53, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4927.64
Subtracting 212 from 220 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 53 fits into 80 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 4927.641
Subtracting 53 from 80 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
53 goes into 270 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4927.6415
Subtract 265 from 270 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
When dividing 50 by 53, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4927.6415
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
500 divided by 53 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 4927.641509
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
When dividing 230 by 53, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4927.6415094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
53 can be fit into 180 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 4927.64150943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 4927.64150943, and the remainder is 2.1e-08.
