We look at the division of 457802 by 99 
The aim is to understand the frequency of 99 in 457802.

Step 1:
4 divided by 99 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 99

Let's proceed to step 2:
99 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 99

Going ahead to step 3:
The number 99 fits into 457 4 times, leaving a remainder of 61.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 61 after subtracting 396 from 457.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 99

Going ahead to step 4:
99 goes into 618 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 46.0
Deduct 594 from 618 and we're left with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 99

Moving on to step 5:
99 goes into 240 2 times with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 462.0
Subtract 198 from 240 to get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 99

On to step 6:
99 can be fit into 422 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 4624.0
If we subtract 396 from 422, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 99 fits into 260 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 4624.2
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
If we divide 620 by 99, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 4624.26
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
99 goes into 260 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 4624.262
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
When dividing 620 by 99, we get 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 4624.2626
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
When dividing 260 by 99, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 4624.26262
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
If we divide 620 by 99, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 4624.262626
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
The number 99 fits into 260 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 4624.2626262
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
99 can be fit into 620 6 times, resulting in a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 4624.26262626
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 4624.26262626, with a leftover of 2.6e-08.
