We look at the division of 168417 by 53 
The aim is to understand the frequency of 53 in 168417.

Advancing to step 1:
If we divide 1 by 53, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 53

Let's proceed to step 2:
The number 53 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 53

On to step 3:
53 goes into 168 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 159 from 168 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 53

On to step 4:
94 divided by 53 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 41 after subtracting 53 from 94.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 53

Going ahead to step 5:
When dividing 411 by 53, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 317.0
Subtracting 371 from 411 leaves us with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 53

On to step 6:
53 can be fit into 407 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 3177.0
If we subtract 371 from 407, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
When dividing 360 by 53, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 3177.6
Subtracting 318 from 360 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
53 can be fit into 420 7 times, resulting in a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 3177.67
If we take 371 away from 420, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
If we divide 490 by 53, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 3177.679
Deduct 477 from 490 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
The number 53 fits into 130 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3177.6792
Subtract 106 from 130 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
The number 53 fits into 240 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 3177.67924
Subtracting 212 from 240 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
53 can be fit into 280 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3177.679245
Deduct 265 from 280 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
53 goes into 150 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 3177.6792452
Subtract 106 from 150 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
When dividing 440 by 53, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3177.67924528
If we take 424 away from 440, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3177.67924528 with a remaining 1.6e-08.
