Let's divide 681403 by 99
The aim is to understand the frequency of 99 in 681403.

On to step 1:
6 divided by 99 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 99

On to step 2:
The number 99 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 99

Going ahead to step 3:
When dividing 681 by 99, we get 6 with a remainder of 87.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 594 from 681 leaves us with 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 99

Let's proceed to step 4:
If we divide 874 by 99, we get 8 and a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 792 from 874 leaves us with 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 99

Advancing to step 5:
The number 99 fits into 820 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 688.0
If we take 792 away from 820, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 99

Let's proceed to step 6:
If we divide 283 by 99, we get 2 and a remainder of 85.
Write down 2 as next digit of the result. 
Result so far: 6882.0
Deduct 198 from 283 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
When dividing 850 by 99, we get 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 6882.8
Subtracting 792 from 850 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
The number 99 fits into 580 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 6882.85
Subtracting 495 from 580 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
When dividing 850 by 99, we get 8 with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 6882.858
If we subtract 792 from 850, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
99 goes into 580 5 times with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 6882.8585
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 11:
If we divide 850 by 99, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 6882.85858
If we subtract 792 from 850, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
When dividing 580 by 99, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 6882.858585
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 13:
The number 99 fits into 850 8 times, leaving a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 6882.8585858
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
99 goes into 580 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 6882.85858585
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 6882.85858585 and a remainder of 8.5e-08.
