We divide 525381 by 53
The aim is to understand the frequency of 53 in 525381.

Step 1:
When dividing 5 by 53, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 53

Going ahead to step 2:
53 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 53

Step 3:
When dividing 525 by 53, we get 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 477 away from 525, we end up with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 53

On to step 4:
53 goes into 483 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 477 from 483 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 53

Going ahead to step 5:
If we divide 68 by 53, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 991.0
If we take 53 away from 68, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 53

Going ahead to step 6:
When dividing 151 by 53, we get 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 9912.0
Subtracting 106 from 151 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
450 divided by 53 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 9912.8
The remainder is 26 after subtracting 424 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
53 can be fit into 260 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 9912.84
If we take 212 away from 260, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
480 divided by 53 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9912.849
If we subtract 477 from 480, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
53 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 9912.849
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
53 goes into 300 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9912.84905
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
The number 53 fits into 350 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 9912.849056
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
53 goes into 320 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 9912.8490566
If we subtract 318 from 320, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 9912.8490566 with a balance of 2e-08.
