We divide 311577 by 99
The aim is to understand the frequency of 99 in 311577.

Advancing to step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 99

Moving on to step 2:
31 divided by 99 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 99

Let's proceed to step 3:
99 goes into 311 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 14 after subtracting 297 from 311.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 99

Step 4:
The number 99 fits into 145 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 99 from 145 and we're left with 46.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 99

Let's proceed to step 5:
When dividing 467 by 99, we get 4 with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 314.0
If we subtract 396 from 467, we get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 99

Moving on to step 6:
When dividing 717 by 99, we get 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 3147.0
Deduct 693 from 717 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 99, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3147.2
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
420 divided by 99 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3147.24
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 99, we get 2 and a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 3147.242
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
99 goes into 420 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 3147.2424
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 99, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3147.24242
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
When dividing 420 by 99, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3147.242424
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
If we divide 240 by 99, we get 2 and a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 3147.2424242
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
If we divide 420 by 99, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3147.24242424
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 3147.24242424 with a remaining 2.4e-08.
