631374 ÷ 99 
The aim is to understand the frequency of 99 in 631374.

Let's proceed to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 99

Advancing to step 2:
63 divided by 99 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 99

Advancing to step 3:
631 divided by 99 is 6 with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 37 after subtracting 594 from 631.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 99

Going ahead to step 4:
373 divided by 99 is 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtract 297 from 373 to get 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 99

Going ahead to step 5:
99 can be fit into 767 7 times, resulting in a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 637.0
Subtract 693 from 767 to get 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 99

Moving on to step 6:
99 goes into 744 7 times with a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 6377.0
Deduct 693 from 744 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
The number 99 fits into 510 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6377.5
The remainder is 15 after subtracting 495 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
The number 99 fits into 150 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 6377.51
If we take 99 away from 150, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
99 goes into 510 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6377.515
The remainder is 15 after subtracting 495 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
99 goes into 150 1 times with a remainder of 51.
The next digit of our result is 1. 
Result so far: 6377.5151
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
510 divided by 99 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6377.51515
If we subtract 495 from 510, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
150 divided by 99 is 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 6377.515151
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 13:
The number 99 fits into 510 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 6377.5151515
Subtract 495 from 510 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
The number 99 fits into 150 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 6377.51515151
Deduct 99 from 150 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

In conclusion, the division gives 6377.51515151 with a balance of 5.1e-08.
