We're dividing 425377 by 53 
The aim is to understand the frequency of 53 in 425377.

Let's proceed to step 1:
When dividing 4 by 53, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 53

Step 2:
The number 53 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 53

Advancing to step 3:
53 can be fit into 425 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 424 from 425 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 53

Going ahead to step 4:
When dividing 13 by 53, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 13 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 53

Let's proceed to step 5:
If we divide 137 by 53, we get 2 and a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 802.0
Subtracting 106 from 137 leaves us with 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 53

Advancing to step 6:
53 goes into 317 5 times with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 8025.0
Subtracting 265 from 317 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
53 can be fit into 520 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 8025.9
Subtract 477 from 520 to get 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.
The number 8 becomes the next digit in our result. 
Result so far: 8025.98
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.

Moving on to step 9:
53 goes into 60 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 8025.981
Subtracting 53 from 60 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On 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: 8025.9811
The remainder is 17 after subtracting 53 from 70.
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 8025.9811, and the remainder is 0.00017.
