839655 ÷ 99 
The aim is to understand the frequency of 99 in 839655.

On to step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 99

Moving on to step 2:
The number 99 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 99

Advancing to step 3:
When dividing 839 by 99, we get 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 792 from 839 to get 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 99

Let's proceed to step 4:
99 can be fit into 476 4 times, resulting in a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 396 from 476 to get 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 99

Let's proceed to step 5:
805 divided by 99 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 848.0
Subtract 792 from 805 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 99

Moving on to step 6:
99 goes into 135 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 8481.0
If we take 99 away from 135, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
360 divided by 99 is 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 8481.3
If we subtract 297 from 360, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 8:
630 divided by 99 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 8481.36
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
99 can be fit into 360 3 times, resulting in a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 8481.363
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 10:
When dividing 630 by 99, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 8481.3636
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
If we divide 360 by 99, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 8481.36363
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 8481.363636
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
If we divide 360 by 99, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 8481.3636363
Subtract 297 from 360 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
The number 99 fits into 630 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 8481.36363636
Deduct 594 from 630 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 8481.36363636 with a remaining 3.6e-08.
