We're dividing 657151 by 99 
The aim is to understand the frequency of 99 in 657151.

Moving on to step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 99

Step 2:
When dividing 65 by 99, we get 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 99

Step 3:
If we divide 657 by 99, we get 6 and a remainder of 63.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 594 from 657 to get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 99

Let's proceed to step 4:
99 goes into 631 6 times with a remainder of 37.
The next digit of our result is 6. 
Result so far: 66.0
The remainder is 37 after subtracting 594 from 631.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 99

Going ahead to step 5:
99 can be fit into 375 3 times, resulting in a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 663.0
If we take 297 away from 375, we end up with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 99

Step 6:
99 can be fit into 781 7 times, resulting in a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 6637.0
Subtract 693 from 781 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 7:
99 can be fit into 880 8 times, resulting in a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 6637.8
If we take 792 away from 880, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 8:
99 goes into 880 8 times with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 6637.88
Subtracting 792 from 880 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 6637.88 and a remainder of 0.088.
