We look at the division of 65392552 by 545 
The aim is to understand the frequency of 545 in 65392552.

Going ahead to step 1:
545 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 545

Step 2:
If we divide 65 by 545, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 545

On to step 3:
545 can be fit into 653 1 times, resulting in a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 545 from 653 leaves us with 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 545

Let's proceed to step 4:
545 can be fit into 1089 1 times, resulting in a remainder of 544.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 545 from 1089, we get 544.
Append the next digit (2) from the dividend to 544 and continue with: 5442 / 545

Step 5:
545 goes into 5442 9 times with a remainder of 537.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtract 4905 from 5442 to get 537.
Take the next digit (5) from the dividend and append it to 537, then repeat: 5375 / 545

Step 6:
545 goes into 5375 9 times with a remainder of 470.
Record the quotient 9 as the next digit in the result. 
Result so far: 1199.0
The remainder is 470 after subtracting 4905 from 5375.
Grab the next digit (5) from the dividend, add it to 470, then carry on: 4705 / 545

Step 7:
545 can be fit into 4705 8 times, resulting in a remainder of 345.
Put 8 as the next digit of the answer. 
Result so far: 11998.0
Subtracting 4360 from 4705 leaves us with 345.
Fetch the next digit (2) from the dividend, attach it to 345 and continue: 3452 / 545

Moving on to step 8:
545 can be fit into 3452 6 times, resulting in a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 119986.0
If we take 3270 away from 3452, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
1820 divided by 545 is 3 with a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 119986.3
If we take 1635 away from 1820, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
The number 545 fits into 1850 3 times, leaving a remainder of 215.
Write down 3 as next digit of the result. 
Result so far: 119986.33
If we subtract 1635 from 1850, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Our division results in 119986.33 with a remaining 0.215.
