99025207 divided by 802 
The aim is to understand the frequency of 802 in 99025207.

Step 1:
802 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 802

On to step 2:
When dividing 99 by 802, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 802

Moving on to step 3:
802 goes into 990 1 times with a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 802 from 990 to get 188.
Grab the next digit (2) from the dividend, add it to 188, then carry on: 1882 / 802

Let's proceed to step 4:
The number 802 fits into 1882 2 times, leaving a remainder of 278.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1604 from 1882, we get 278.
Append the next digit (5) from the dividend to 278 and continue with: 2785 / 802

Going ahead to step 5:
802 can be fit into 2785 3 times, resulting in a remainder of 379.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 2406 from 2785 and we're left with 379.
Include the next digit (2) from the dividend after 379, then repeat: 3792 / 802

On to step 6:
3792 divided by 802 is 4 with a remainder of 584.
The next digit of our result is 4. 
Result so far: 1234.0
If we subtract 3208 from 3792, we get 584.
Bring next digit (0) of the dividend behind the 584 and repeat the process: 5840 / 802

Let's proceed to step 7:
802 goes into 5840 7 times with a remainder of 226.
Write down 7 as next digit of the result. 
Result so far: 12347.0
If we subtract 5614 from 5840, we get 226.
Bring next digit (7) of the dividend behind the 226 and repeat the process: 2267 / 802

Step 8:
When dividing 2267 by 802, we get 2 with a remainder of 663.
The number 2 becomes the next digit in our result. 
Result so far: 123472.0
If we subtract 1604 from 2267, we get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Moving on to step 9:
When dividing 6630 by 802, we get 8 with a remainder of 214.
The next digit of our result is 8. 
Result so far: 123472.8
If we subtract 6416 from 6630, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
802 can be fit into 2140 2 times, resulting in a remainder of 536.
Record the quotient 2 as the next digit in the result. 
Result so far: 123472.82
Subtracting 1604 from 2140 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 11:
The number 802 fits into 5360 6 times, leaving a remainder of 548.
The number 6 becomes the next digit in our result. 
Result so far: 123472.826
If we take 4812 away from 5360, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 12:
5480 divided by 802 is 6 with a remainder of 668.
The next digit of our result is 6. 
Result so far: 123472.8266
If we subtract 4812 from 5480, we get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

After the division, we end up with 123472.8266 and a remainder of 0.00668.
