459163 ÷ 99 
The aim is to understand the frequency of 99 in 459163.

On to step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 99

Moving on to step 2:
45 divided by 99 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 99

Advancing to step 3:
459 divided by 99 is 4 with a remainder of 63.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 396 from 459 to get 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 99

Going ahead to step 4:
631 divided by 99 is 6 with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 594 from 631 leaves us with 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 99

On to step 5:
99 goes into 376 3 times with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 463.0
If we take 297 away from 376, we end up with 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 99

On to step 6:
The number 99 fits into 793 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 4638.0
Subtract 792 from 793 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 99, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4638.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 99 fits into 100 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4638.01
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
If we divide 10 by 99, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4638.01
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
99 can be fit into 100 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 4638.0101
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
When dividing 10 by 99, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4638.0101
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 99 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 4638.010101
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
The number 99 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4638.010101
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 99, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 4638.01010101
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 4638.01010101 with a remainder of 1e-09.
