We look at the division of 570402 by 99 
The aim is to understand the frequency of 99 in 570402.

On to step 1:
When dividing 5 by 99, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 99

On to step 2:
When dividing 57 by 99, we get 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 99

Going ahead to step 3:
If we divide 570 by 99, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 5.0
If we take 495 away from 570, we end up with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 99

Let's proceed to step 4:
When dividing 754 by 99, we get 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtract 693 from 754 to get 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 99

Going ahead to step 5:
99 goes into 610 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 576.0
Subtracting 594 from 610 leaves us with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 99

Advancing to step 6:
99 goes into 162 1 times with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 5761.0
Subtracting 99 from 162 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
If we divide 630 by 99, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 5761.6
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
The number 99 fits into 360 3 times, leaving a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 5761.63
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
630 divided by 99 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 5761.636
If we take 594 away from 630, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
360 divided by 99 is 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 5761.6363
If we take 297 away from 360, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 11:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 5761.63636
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 99 is 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 5761.636363
If we take 297 away from 360, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 13:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 5761.6363636
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
99 goes into 360 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 5761.63636363
If we take 297 away from 360, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Our division results in 5761.63636363 with a remaining 6.3e-08.
