We're dividing 58649 by 99 
The aim is to understand the frequency of 99 in 58649.

Step 1:
When dividing 5 by 99, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 99

On to step 2:
When dividing 58 by 99, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 99

Going ahead to step 3:
99 can be fit into 586 5 times, resulting in a remainder of 91.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 495 away from 586, we end up with 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 99

Let's proceed to step 4:
If we divide 914 by 99, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Deduct 891 from 914 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 99

Step 5:
99 goes into 239 2 times with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 592.0
If we subtract 198 from 239, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 6:
If we divide 410 by 99, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 592.4
Deduct 396 from 410 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
99 goes into 140 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 592.41
If we subtract 99 from 140, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
410 divided by 99 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 592.414
If we take 396 away from 410, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
If we divide 140 by 99, we get 1 and a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 592.4141
Deduct 99 from 140 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
When dividing 410 by 99, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 592.41414
If we take 396 away from 410, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
The number 99 fits into 140 1 times, leaving a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 592.414141
Subtract 99 from 140 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
The number 99 fits into 410 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 592.4141414
Deduct 396 from 410 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 99, we get 1 and a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 592.41414141
If we take 99 away from 140, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 592.41414141 with a remaining 4.1e-08.
