Let's divide 75817 by 53
The aim is to understand the frequency of 53 in 75817.

Moving on to step 1:
53 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 53

Moving on to step 2:
When dividing 75 by 53, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 75, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 53

Step 3:
228 divided by 53 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 212 from 228, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 53

Going ahead to step 4:
If we divide 161 by 53, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 143.0
Subtracting 159 from 161 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 53

Going ahead to step 5:
If we divide 27 by 53, we get 0 and a remainder of 27.
The next digit of our result is 0. 
Result so far: 1430.0
Deduct 0 from 27 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.

Advancing to step 6:
If we divide 270 by 53, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1430.5
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.

Moving on to step 7:
50 divided by 53 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1430.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 53 is 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 1430.509
Deduct 477 from 500 and we're left 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.

Let's proceed to step 9:
53 can be fit into 230 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1430.5094
If we subtract 212 from 230, we 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.

Let's proceed to step 10:
If we divide 180 by 53, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 1430.50943
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
210 divided by 53 is 3 with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 1430.509433
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 1430.509433 and a remainder of 5.1e-06.
