We look at the division of 61457 by 99 
The aim is to understand the frequency of 99 in 61457.

Moving on to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 99

Moving on to step 2:
If we divide 61 by 99, we get 0 and a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 99

Moving on to step 3:
When dividing 614 by 99, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 20 after subtracting 594 from 614.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 99

Let's proceed to step 4:
205 divided by 99 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we subtract 198 from 205, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 99

Step 5:
99 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 620.0
Subtracting 0 from 77 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 6:
When dividing 770 by 99, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 620.7
If we take 693 away from 770, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 7:
99 goes into 770 7 times with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 620.77
Subtract 693 from 770 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Our division results in 620.77 with a remaining 0.077.
