We're dividing 51308355 by 635 
The aim is to understand the frequency of 635 in 51308355.

Step 1:
The number 635 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 635

Advancing to step 2:
635 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 635

Let's proceed to step 3:
635 goes into 513 0 times with a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 513, we end up with 513.
Include the next digit (0) from the dividend after 513, then repeat: 5130 / 635

Let's proceed to step 4:
635 goes into 5130 8 times with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5080 away from 5130, we end up with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 635

Advancing to step 5:
635 goes into 508 0 times with a remainder of 508.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we take 0 away from 508, we end up with 508.
Take the next digit (3) from the dividend and append it to 508, then repeat: 5083 / 635

Step 6:
635 can be fit into 5083 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 808.0
Subtracting 5080 from 5083 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 635

Moving on to step 7:
635 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 8080.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 635

Going ahead to step 8:
If we divide 355 by 635, we get 0 and a remainder of 355.
Put 0 as the next digit of the answer. 
Result so far: 80800.0
Subtracting 0 from 355 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 9:
When dividing 3550 by 635, we get 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 80800.5
Deduct 3175 from 3550 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 10:
3750 divided by 635 is 5 with a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 80800.55
If we take 3175 away from 3750, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

In conclusion, the division gives 80800.55 with a balance of 0.575.
