We're dividing 78753554 by 247 
The aim is to understand the frequency of 247 in 78753554.

Moving on to step 1:
When dividing 7 by 247, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 247

Going ahead to step 2:
The number 247 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 247

On to step 3:
247 can be fit into 787 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 741 from 787 to get 46.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 247

Advancing to step 4:
When dividing 465 by 247, we get 1 with a remainder of 218.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 247 away from 465, we end up with 218.
Append the next digit (3) from the dividend to 218 and continue with: 2183 / 247

On to step 5:
If we divide 2183 by 247, we get 8 and a remainder of 207.
Write down 8 as next digit of the result. 
Result so far: 318.0
The remainder is 207 after subtracting 1976 from 2183.
Include the next digit (5) from the dividend after 207, then repeat: 2075 / 247

Going ahead to step 6:
2075 divided by 247 is 8 with a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 3188.0
If we take 1976 away from 2075, we end up with 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 247

Moving on to step 7:
When dividing 995 by 247, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 31884.0
Subtracting 988 from 995 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 247

Going ahead to step 8:
247 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 318840.0
Subtracting 0 from 74 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
When dividing 740 by 247, we get 2 with a remainder of 246.
Put 2 as the next digit of the answer. 
Result so far: 318840.2
The remainder is 246 after subtracting 494 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
When dividing 2460 by 247, we get 9 with a remainder of 237.
Write down 9 as next digit of the result. 
Result so far: 318840.29
Deduct 2223 from 2460 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 11:
If we divide 2370 by 247, we get 9 and a remainder of 147.
The next digit of our result is 9. 
Result so far: 318840.299
If we take 2223 away from 2370, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

After the division, we end up with 318840.299 and a remainder of 0.0147.
