17305240 ÷ 53 
The aim is to understand the frequency of 53 in 17305240.

Moving on to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 53

Going ahead to step 2:
53 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 53

Moving on to step 3:
If we divide 173 by 53, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 159 from 173 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 53

Let's proceed to step 4:
140 divided by 53 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 106 from 140 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 53

On to step 5:
53 can be fit into 345 6 times, resulting in a remainder of 27.
The next digit of our result is 6. 
Result so far: 326.0
The remainder is 27 after subtracting 318 from 345.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 53

Let's proceed to step 6:
53 goes into 272 5 times with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 3265.0
Subtracting 265 from 272 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 53

Advancing to step 7:
74 divided by 53 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 32651.0
Subtract 53 from 74 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 53

Let's proceed to step 8:
210 divided by 53 is 3 with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 326513.0
If we subtract 159 from 210, we 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.

Going ahead to step 9:
When dividing 510 by 53, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 326513.9
Deduct 477 from 510 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
53 can be fit into 330 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 326513.96
If we subtract 318 from 330, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 53 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 326513.962
Subtracting 106 from 120 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
140 divided by 53 is 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 326513.9622
The remainder is 34 after subtracting 106 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 326513.9622 and a remainder of 0.00034.
