We look at the division of 489904 by 53 
The aim is to understand the frequency of 53 in 489904.

Going ahead to step 1:
53 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 53

Step 2:
The number 53 fits into 48 0 times, leaving a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 53

Advancing to step 3:
53 goes into 489 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 12 after subtracting 477 from 489.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 53

Going ahead to step 4:
When dividing 129 by 53, we get 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtracting 106 from 129 leaves us with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 53

On to step 5:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 924.0
Subtracting 212 from 230 leaves us with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 53

Let's proceed to step 6:
53 goes into 184 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 9243.0
If we take 159 away from 184, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
If we divide 250 by 53, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 9243.4
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
53 can be fit into 380 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 9243.47
If we take 371 away from 380, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
53 can be fit into 90 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 9243.471
Subtracting 53 from 90 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
The number 53 fits into 370 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 9243.4716
The remainder is 52 after subtracting 318 from 370.
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 11:
When dividing 520 by 53, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 9243.47169
If we subtract 477 from 520, we 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.

Step 12:
When dividing 430 by 53, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 9243.471698
Deduct 424 from 430 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
When dividing 60 by 53, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 9243.4716981
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
When dividing 70 by 53, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 9243.47169811
Deduct 53 from 70 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 9243.47169811 with a balance of 1.7e-08.
