78248117 ÷ 307 
The aim is to understand the frequency of 307 in 78248117.

On to step 1:
307 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 307

Step 2:
When dividing 78 by 307, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 307

Advancing to step 3:
307 can be fit into 782 2 times, resulting in a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 614 from 782 to get 168.
Bring next digit (4) of the dividend behind the 168 and repeat the process: 1684 / 307

Let's proceed to step 4:
307 goes into 1684 5 times with a remainder of 149.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 149 after subtracting 1535 from 1684.
Include the next digit (8) from the dividend after 149, then repeat: 1498 / 307

Advancing to step 5:
307 goes into 1498 4 times with a remainder of 270.
Put 4 as the next digit of the answer. 
Result so far: 254.0
The remainder is 270 after subtracting 1228 from 1498.
Bring next digit (1) of the dividend behind the 270 and repeat the process: 2701 / 307

Let's proceed to step 6:
When dividing 2701 by 307, we get 8 with a remainder of 245.
The next digit of our result is 8. 
Result so far: 2548.0
Subtracting 2456 from 2701 leaves us with 245.
Append the next digit (1) from the dividend to 245 and continue with: 2451 / 307

Going ahead to step 7:
307 goes into 2451 7 times with a remainder of 302.
Use 7 as the next digit of our solution. 
Result so far: 25487.0
Subtracting 2149 from 2451 leaves us with 302.
Fetch the next digit (7) from the dividend, attach it to 302 and continue: 3027 / 307

Moving on to step 8:
307 goes into 3027 9 times with a remainder of 264.
Record the quotient 9 as the next digit in the result. 
Result so far: 254879.0
Subtract 2763 from 3027 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
When dividing 2640 by 307, we get 8 with a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 254879.8
Subtract 2456 from 2640 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 10:
If we divide 1840 by 307, we get 5 and a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 254879.85
Subtracting 1535 from 1840 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 11:
307 goes into 3050 9 times with a remainder of 287.
The next digit of our result is 9. 
Result so far: 254879.859
The remainder is 287 after subtracting 2763 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 12:
307 can be fit into 2870 9 times, resulting in a remainder of 107.
Use 9 as the next digit of our solution. 
Result so far: 254879.8599
Subtracting 2763 from 2870 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 254879.8599 with a remainder of 0.00107.
