2354409 ÷ 53 
The aim is to understand the frequency of 53 in 2354409.

On to step 1:
2 divided by 53 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 53

Let's proceed to step 2:
53 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 53

On to step 3:
The number 53 fits into 235 4 times, leaving a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 23 after subtracting 212 from 235.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 53

Step 4:
When dividing 234 by 53, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 212 from 234, we get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 53

Let's proceed to step 5:
53 can be fit into 224 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 444.0
If we take 212 away from 224, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 53

Advancing to step 6:
When dividing 120 by 53, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 4442.0
If we subtract 106 from 120, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 53

Going ahead to step 7:
53 can be fit into 149 2 times, resulting in a remainder of 43.
The next digit of our result is 2. 
Result so far: 44422.0
If we take 106 away from 149, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
The number 53 fits into 430 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 44422.8
Subtracting 424 from 430 leaves us 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.

Step 9:
If we divide 60 by 53, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 44422.81
Subtract 53 from 60 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
53 goes into 70 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 44422.811
Subtracting 53 from 70 leaves us 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.

The quotient of the division is 44422.811, and the remainder is 0.0017.
