624769 divided by 99 
The aim is to understand the frequency of 99 in 624769.

Moving on to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 99

On to step 2:
62 divided by 99 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 99

On to step 3:
If we divide 624 by 99, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 30 after subtracting 594 from 624.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 99

Going ahead to step 4:
When dividing 307 by 99, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 297 from 307 leaves us with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 99

Advancing to step 5:
99 goes into 106 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 631.0
Subtracting 99 from 106 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 99

Let's proceed to step 6:
The number 99 fits into 79 0 times, leaving a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 6310.0
The remainder is 79 after subtracting 0 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
If we divide 790 by 99, we get 7 and a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 6310.7
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 8:
970 divided by 99 is 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 6310.79
If we take 891 away from 970, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
When dividing 790 by 99, we get 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 6310.797
Subtracting 693 from 790 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 10:
99 can be fit into 970 9 times, resulting in a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 6310.7979
Deduct 891 from 970 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
If we divide 790 by 99, we get 7 and a remainder of 97.
The next digit of our result is 7. 
Result so far: 6310.79797
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 12:
99 goes into 970 9 times with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 6310.797979
The remainder is 79 after subtracting 891 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 13:
If we divide 790 by 99, we get 7 and a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 6310.7979797
Subtract 693 from 790 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 14:
99 can be fit into 970 9 times, resulting in a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 6310.79797979
If we subtract 891 from 970, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The quotient of the division is 6310.79797979, and the remainder is 7.9e-08.
