We're dividing 806697 by 99 
The aim is to understand the frequency of 99 in 806697.

Step 1:
8 divided by 99 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 99

Let's proceed to step 2:
If we divide 80 by 99, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 99

Advancing to step 3:
When dividing 806 by 99, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 792 from 806 to get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 99

Going ahead to step 4:
146 divided by 99 is 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 99 away from 146, we end up with 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 99

Going ahead to step 5:
If we divide 479 by 99, we get 4 and a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 814.0
Subtract 396 from 479 to get 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 99

Advancing to step 6:
The number 99 fits into 837 8 times, leaving a remainder of 45.
The next digit of our result is 8. 
Result so far: 8148.0
Subtracting 792 from 837 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
450 divided by 99 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 8148.4
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
99 goes into 540 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 8148.45
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
When dividing 450 by 99, we get 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 8148.454
The remainder is 54 after subtracting 396 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
540 divided by 99 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 8148.4545
Deduct 495 from 540 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
When dividing 450 by 99, we get 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 8148.45454
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
540 divided by 99 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 8148.454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
450 divided by 99 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 8148.4545454
The remainder is 54 after subtracting 396 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
The number 99 fits into 540 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 8148.45454545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.
