Let's divide 104912 by 99
The aim is to understand the frequency of 99 in 104912.

Let's proceed to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 99

Let's proceed to step 2:
If we divide 10 by 99, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 99

Moving on to step 3:
If we divide 104 by 99, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 99 from 104 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 99

On to step 4:
The number 99 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 59, we get 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 99

Step 5:
When dividing 591 by 99, we get 5 with a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 495 away from 591, we end up with 96.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 99

On to step 6:
When dividing 962 by 99, we get 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 1059.0
The remainder is 71 after subtracting 891 from 962.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
710 divided by 99 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 1059.7
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
99 can be fit into 170 1 times, resulting in a remainder of 71.
The next digit of our result is 1. 
Result so far: 1059.71
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
When dividing 710 by 99, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1059.717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
When dividing 170 by 99, we get 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1059.7171
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 11:
99 can be fit into 710 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1059.71717
Subtracting 693 from 710 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 1059.717171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 13:
99 can be fit into 710 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 1059.7171717
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
If we divide 170 by 99, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1059.71717171
If we subtract 99 from 170, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 1059.71717171 and a remainder of 7.1e-08.
