Let's divide 628845 by 99
The aim is to understand the frequency of 99 in 628845.

Step 1:
6 divided by 99 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 99

Moving on to step 2:
99 can be fit into 62 0 times, resulting in a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 99

Moving on to step 3:
99 goes into 628 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 594 from 628 and we're left with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 99

Moving on to step 4:
If we divide 348 by 99, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtracting 297 from 348 leaves us with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 99

Advancing to step 5:
514 divided by 99 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 635.0
If we take 495 away from 514, we end up with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 99

On to step 6:
99 can be fit into 195 1 times, resulting in a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 6351.0
If we subtract 99 from 195, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 7:
The number 99 fits into 960 9 times, leaving a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 6351.9
If we take 891 away from 960, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 8:
99 goes into 690 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 6351.96
The remainder is 96 after subtracting 594 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
99 goes into 960 9 times with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 6351.969
The remainder is 69 after subtracting 891 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
If we divide 690 by 99, we get 6 and a remainder of 96.
The next digit of our result is 6. 
Result so far: 6351.9696
Subtract 594 from 690 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
If we divide 960 by 99, we get 9 and a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 6351.96969
The remainder is 69 after subtracting 891 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
When dividing 690 by 99, we get 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 6351.969696
Deduct 594 from 690 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
If we divide 960 by 99, we get 9 and a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 6351.9696969
Deduct 891 from 960 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 14:
690 divided by 99 is 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 6351.96969696
If we subtract 594 from 690, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 6351.96969696 with a remainder of 9.6e-08.
