We're dividing 54619359 by 99 
The aim is to understand the frequency of 99 in 54619359.

Step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 99

On to step 2:
If we divide 54 by 99, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 99

On to step 3:
If we divide 546 by 99, we get 5 and a remainder of 51.
The next digit of our result is 5. 
Result so far: 5.0
If we take 495 away from 546, we end up with 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 99

Moving on to step 4:
The number 99 fits into 511 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we take 495 away from 511, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 99

Let's proceed to step 5:
The number 99 fits into 169 1 times, leaving a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 551.0
If we take 99 away from 169, we end up with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 99

Moving on to step 6:
When dividing 703 by 99, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 5517.0
The remainder is 10 after subtracting 693 from 703.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 99

Advancing to step 7:
99 can be fit into 105 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 55171.0
Deduct 99 from 105 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 99

Going ahead to step 8:
When dividing 69 by 99, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 551710.0
Deduct 0 from 69 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.

Step 9:
99 goes into 690 6 times with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 551710.6
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 10:
960 divided by 99 is 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 551710.69
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
99 goes into 690 6 times with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 551710.696
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.

Moving on to step 12:
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: 551710.6969
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.

Advancing to step 13:
99 can be fit into 690 6 times, resulting in a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 551710.69696
Subtracting 594 from 690 leaves us 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 14:
When dividing 960 by 99, we get 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 551710.696969
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 15:
99 can be fit into 690 6 times, resulting in a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 551710.6969696
Subtracting 594 from 690 leaves us 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.

Step 16:
960 divided by 99 is 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 551710.69696969
Subtract 891 from 960 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 551710.69696969, and the remainder is 6.9e-08.
