99152775 ÷ 249 
The aim is to understand the frequency of 249 in 99152775.

Step 1:
When dividing 9 by 249, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 249

Let's proceed to step 2:
The number 249 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 249

Let's proceed to step 3:
If we divide 991 by 249, we get 3 and a remainder of 244.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 747 from 991 to get 244.
Append the next digit (5) from the dividend to 244 and continue with: 2445 / 249

Step 4:
2445 divided by 249 is 9 with a remainder of 204.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 2241 from 2445 leaves us with 204.
Append the next digit (2) from the dividend to 204 and continue with: 2042 / 249

On to step 5:
When dividing 2042 by 249, we get 8 with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 398.0
Deduct 1992 from 2042 and we're left with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 249

On to step 6:
When dividing 507 by 249, we get 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 3982.0
Deduct 498 from 507 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 249

Going ahead to step 7:
When dividing 97 by 249, we get 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 39820.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (5) from the dividend, attach it to 97 and continue: 975 / 249

Moving on to step 8:
When dividing 975 by 249, we get 3 with a remainder of 228.
The next digit of our result is 3. 
Result so far: 398203.0
Subtracting 747 from 975 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 9:
The number 249 fits into 2280 9 times, leaving a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 398203.9
If we subtract 2241 from 2280, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
When dividing 390 by 249, we get 1 with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 398203.91
Deduct 249 from 390 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 11:
When dividing 1410 by 249, we get 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 398203.915
Deduct 1245 from 1410 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 12:
1650 divided by 249 is 6 with a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 398203.9156
Deduct 1494 from 1650 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 13:
1560 divided by 249 is 6 with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 398203.91566
If we take 1494 away from 1560, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 398203.91566 and a remainder of 6.6e-05.
