750456 divided by 99 
The aim is to understand the frequency of 99 in 750456.

Step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 99

Going ahead to step 2:
99 goes into 75 0 times with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (0) from the dividend, add it to 75, then carry on: 750 / 99

Advancing to step 3:
If we divide 750 by 99, we get 7 and a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 693 away from 750, we end up with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 99

Step 4:
If we divide 574 by 99, we get 5 and a remainder of 79.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 495 from 574 leaves us with 79.
Fetch the next digit (5) from the dividend, attach it to 79 and continue: 795 / 99

Let's proceed to step 5:
If we divide 795 by 99, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 758.0
Subtracting 792 from 795 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 99

Advancing to step 6:
When dividing 36 by 99, we get 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 7580.0
Subtracting 0 from 36 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.

Step 7:
The number 99 fits into 360 3 times, leaving a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 7580.3
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.

Moving on to step 8:
99 can be fit into 630 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 7580.36
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.

Moving on to step 9:
The number 99 fits into 360 3 times, leaving a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 7580.363
The remainder is 63 after subtracting 297 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 10:
99 goes into 630 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 7580.3636
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.

Going ahead to step 11:
360 divided by 99 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 7580.36363
If we take 297 away from 360, we end up 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.

Advancing to step 12:
99 can be fit into 630 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 7580.363636
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:
When dividing 360 by 99, we get 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 7580.3636363
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.

Moving on to step 14:
99 can be fit into 630 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 7580.36363636
If we subtract 594 from 630, we 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.

After the division, we end up with 7580.36363636 and a remainder of 3.6e-08.
