We divide 55644413 by 516
The aim is to understand the frequency of 516 in 55644413.

Step 1:
If we divide 5 by 516, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 516

Step 2:
When dividing 55 by 516, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 516

Step 3:
The number 516 fits into 556 1 times, leaving a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 40 after subtracting 516 from 556.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 516

Going ahead to step 4:
The number 516 fits into 404 0 times, leaving a remainder of 404.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 404 leaves us with 404.
Take the next digit (4) from the dividend and append it to 404, then repeat: 4044 / 516

Step 5:
516 can be fit into 4044 7 times, resulting in a remainder of 432.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 3612 from 4044 leaves us with 432.
Append the next digit (4) from the dividend to 432 and continue with: 4324 / 516

Going ahead to step 6:
4324 divided by 516 is 8 with a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 1078.0
Subtracting 4128 from 4324 leaves us with 196.
Append the next digit (1) from the dividend to 196 and continue with: 1961 / 516

Moving on to step 7:
The number 516 fits into 1961 3 times, leaving a remainder of 413.
Record the quotient 3 as the next digit in the result. 
Result so far: 10783.0
If we subtract 1548 from 1961, we get 413.
Bring next digit (3) of the dividend behind the 413 and repeat the process: 4133 / 516

Let's proceed to step 8:
The number 516 fits into 4133 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 107838.0
Subtracting 4128 from 4133 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 516 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 107838.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 516, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 107838.0
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 107838.0 with a remaining 0.5.
