96013870 ÷ 249 
The aim is to understand the frequency of 249 in 96013870.

Moving on to step 1:
When dividing 9 by 249, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 249

Moving on to step 2:
The number 249 fits into 96 0 times, leaving a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 96, we get 96.
Bring next digit (0) of the dividend behind the 96 and repeat the process: 960 / 249

On to step 3:
249 can be fit into 960 3 times, resulting in a remainder of 213.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 747 from 960 leaves us with 213.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 249

Step 4:
249 goes into 2131 8 times with a remainder of 139.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 1992 from 2131 leaves us with 139.
Append the next digit (3) from the dividend to 139 and continue with: 1393 / 249

Advancing to step 5:
If we divide 1393 by 249, we get 5 and a remainder of 148.
Record the quotient 5 as the next digit in the result. 
Result so far: 385.0
The remainder is 148 after subtracting 1245 from 1393.
Append the next digit (8) from the dividend to 148 and continue with: 1488 / 249

Step 6:
The number 249 fits into 1488 5 times, leaving a remainder of 243.
Put 5 as the next digit of the answer. 
Result so far: 3855.0
The remainder is 243 after subtracting 1245 from 1488.
Take the next digit (7) from the dividend and append it to 243, then repeat: 2437 / 249

Going ahead to step 7:
249 can be fit into 2437 9 times, resulting in a remainder of 196.
Use 9 as the next digit of our solution. 
Result so far: 38559.0
Subtract 2241 from 2437 to get 196.
Include the next digit (0) from the dividend after 196, then repeat: 1960 / 249

Advancing to step 8:
The number 249 fits into 1960 7 times, leaving a remainder of 217.
Use 7 as the next digit of our solution. 
Result so far: 385597.0
Subtract 1743 from 1960 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 9:
249 goes into 2170 8 times with a remainder of 178.
The next digit of our result is 8. 
Result so far: 385597.8
If we subtract 1992 from 2170, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
249 goes into 1780 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 385597.87
Subtract 1743 from 1780 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
If we divide 370 by 249, we get 1 and a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 385597.871
Subtract 249 from 370 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 12:
1210 divided by 249 is 4 with a remainder of 214.
Write down 4 as next digit of the result. 
Result so far: 385597.8714
If we subtract 996 from 1210, 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 13:
2140 divided by 249 is 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 385597.87148
If we subtract 1992 from 2140, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 14:
The number 249 fits into 1480 5 times, leaving a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 385597.871485
The remainder is 235 after subtracting 1245 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 15:
If we divide 2350 by 249, we get 9 and a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 385597.8714859
Subtract 2241 from 2350 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 16:
The number 249 fits into 1090 4 times, leaving a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 385597.87148594
If we take 996 away from 1090, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final outcome is 385597.87148594, with a leftover of 9.4e-08.
