We're dividing 657477 by 99 
The aim is to understand the frequency of 99 in 657477.

Let's proceed to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 99

On to step 2:
99 can be fit into 65 0 times, resulting in a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 99

Let's proceed to step 3:
99 goes into 657 6 times with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 594 from 657, we get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 99

Let's proceed to step 4:
The number 99 fits into 634 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 594 from 634 and we're left with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 99

On to step 5:
99 goes into 407 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 664.0
Subtract 396 from 407 to get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 99

Going ahead to step 6:
99 goes into 117 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 6641.0
The remainder is 18 after subtracting 99 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 99, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 6641.1
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 8:
When dividing 810 by 99, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 6641.18
Subtract 792 from 810 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
180 divided by 99 is 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 6641.181
Subtract 99 from 180 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 10:
When dividing 810 by 99, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 6641.1818
If we take 792 away from 810, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
180 divided by 99 is 1 with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 6641.18181
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 12:
810 divided by 99 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 6641.181818
The remainder is 18 after subtracting 792 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
99 can be fit into 180 1 times, resulting in a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 6641.1818181
Deduct 99 from 180 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 14:
99 goes into 810 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 6641.18181818
If we subtract 792 from 810, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 6641.18181818 and a remainder of 1.8e-08.
