807270 ÷ 99 
The aim is to understand the frequency of 99 in 807270.

Moving on to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 99

Let's proceed to step 2:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 99

On to step 3:
99 goes into 807 8 times with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 792 from 807 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 99

Advancing to step 4:
152 divided by 99 is 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 53 after subtracting 99 from 152.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 99

Going ahead to step 5:
99 can be fit into 537 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 815.0
Subtract 495 from 537 to get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 99

Let's proceed to step 6:
When dividing 420 by 99, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 8154.0
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 99, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 8154.2
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
99 can be fit into 420 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 8154.24
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 8154.242
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
When dividing 420 by 99, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8154.2424
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 8154.24242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 99 fits into 420 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 8154.242424
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
99 goes into 240 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 8154.2424242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
When dividing 420 by 99, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8154.24242424
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 8154.24242424, and the remainder is 2.4e-08.
