Let's divide 812908 by 99
The aim is to understand the frequency of 99 in 812908.

Step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 99

On to step 2:
The number 99 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 99

Let's proceed to step 3:
99 can be fit into 812 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 792 from 812, we get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 99

Advancing to step 4:
209 divided by 99 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 198 from 209 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 99

Going ahead to step 5:
99 goes into 110 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 821.0
Subtracting 99 from 110 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 99

Advancing to step 6:
118 divided by 99 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8211.0
Subtract 99 from 118 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 99, we get 1 and a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 8211.1
If we subtract 99 from 190, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 8:
910 divided by 99 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 8211.19
Subtract 891 from 910 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
99 goes into 190 1 times with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 8211.191
Subtract 99 from 190 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 10:
910 divided by 99 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 8211.1919
Subtracting 891 from 910 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
190 divided by 99 is 1 with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 8211.19191
If we subtract 99 from 190, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 12:
99 goes into 910 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 8211.191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
The number 99 fits into 190 1 times, leaving a remainder of 91.
The next digit of our result is 1. 
Result so far: 8211.1919191
Deduct 99 from 190 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 14:
When dividing 910 by 99, we get 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 8211.19191919
Subtract 891 from 910 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 8211.19191919, and the remainder is 1.9e-08.
