We look at the division of 907500 by 53 
The aim is to understand the frequency of 53 in 907500.

Going ahead to step 1:
When dividing 9 by 53, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 53

Step 2:
53 can be fit into 90 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 53 from 90, we get 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 53

Going ahead to step 3:
When dividing 377 by 53, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 371 away from 377, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 53

Let's proceed to step 4:
The number 53 fits into 65 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 53 from 65 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 53

Let's proceed to step 5:
When dividing 120 by 53, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 1712.0
Subtracting 106 from 120 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 53

Advancing to step 6:
53 goes into 140 2 times with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 17122.0
Subtracting 106 from 140 leaves us 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.

Moving on to step 7:
340 divided by 53 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 17122.6
If we take 318 away from 340, we end up 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.
The number 4 becomes the next digit in our result. 
Result so far: 17122.64
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.

Step 9:
The number 53 fits into 80 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 17122.641
Deduct 53 from 80 and we're left 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.

Let's proceed to step 10:
If we divide 270 by 53, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 17122.6415
Deduct 265 from 270 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
53 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 17122.6415
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
53 can be fit into 500 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 17122.641509
The remainder is 23 after subtracting 477 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
When dividing 230 by 53, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 17122.6415094
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.
Put 3 as the next digit of the answer. 
Result so far: 17122.64150943
The remainder is 21 after subtracting 159 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 17122.64150943 with a remainder of 2.1e-08.
