Let's divide 601131 by 99
The aim is to understand the frequency of 99 in 601131.

Going ahead to step 1:
99 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 99

Step 2:
If we divide 60 by 99, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 99

Going ahead to step 3:
99 goes into 601 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 594 from 601 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 99

On to step 4:
99 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtract 0 from 71 to get 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 99

On to step 5:
When dividing 713 by 99, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 607.0
If we take 693 away from 713, we end up with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 99

Going ahead to step 6:
201 divided by 99 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 6072.0
The remainder is 3 after subtracting 198 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 99 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6072.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 99, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6072.03
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
99 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 6072.03
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
99 goes into 300 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 6072.0303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 99, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6072.0303
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 99 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 6072.030303
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
When dividing 30 by 99, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6072.030303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 99 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 6072.03030303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 6072.03030303 with a balance of 3e-09.
