78031020 divided by 249 
The aim is to understand the frequency of 249 in 78031020.

Advancing to step 1:
The number 249 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 249

Advancing to step 2:
249 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 249

Let's proceed to step 3:
249 can be fit into 780 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 747 from 780 leaves us with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 249

On to step 4:
249 can be fit into 333 1 times, resulting in a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 249 away from 333, we end up with 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 249

Step 5:
The number 249 fits into 841 3 times, leaving a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
Subtracting 747 from 841 leaves us with 94.
Bring next digit (0) of the dividend behind the 94 and repeat the process: 940 / 249

Moving on to step 6:
249 can be fit into 940 3 times, resulting in a remainder of 193.
The next digit of our result is 3. 
Result so far: 3133.0
The remainder is 193 after subtracting 747 from 940.
Include the next digit (2) from the dividend after 193, then repeat: 1932 / 249

Advancing to step 7:
1932 divided by 249 is 7 with a remainder of 189.
Put 7 as the next digit of the answer. 
Result so far: 31337.0
Subtracting 1743 from 1932 leaves us with 189.
Include the next digit (0) from the dividend after 189, then repeat: 1890 / 249

Step 8:
The number 249 fits into 1890 7 times, leaving a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 313377.0
Subtract 1743 from 1890 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 9:
249 can be fit into 1470 5 times, resulting in a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 313377.5
The remainder is 225 after subtracting 1245 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
249 can be fit into 2250 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 313377.59
Subtract 2241 from 2250 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
249 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 313377.59
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
249 goes into 900 3 times with a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 313377.5903
If we take 747 away from 900, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 13:
When dividing 1530 by 249, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 313377.59036
Subtract 1494 from 1530 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
If we divide 360 by 249, we get 1 and a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 313377.590361
If we take 249 away from 360, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 15:
249 can be fit into 1110 4 times, resulting in a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 313377.5903614
Subtract 996 from 1110 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 16:
249 can be fit into 1140 4 times, resulting in a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 313377.59036144
Subtract 996 from 1140 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 313377.59036144 and a remainder of 1.44e-07.
