We look at the division of 71680250 by 248 
The aim is to understand the frequency of 248 in 71680250.

Step 1:
If we divide 7 by 248, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 248

Step 2:
When dividing 71 by 248, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 248

Step 3:
If we divide 716 by 248, we get 2 and a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 496 from 716 leaves us with 220.
Bring next digit (8) of the dividend behind the 220 and repeat the process: 2208 / 248

Advancing to step 4:
248 goes into 2208 8 times with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 1984 away from 2208, we end up with 224.
Include the next digit (0) from the dividend after 224, then repeat: 2240 / 248

Advancing to step 5:
248 can be fit into 2240 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
Subtract 2232 from 2240 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 248

Moving on to step 6:
248 goes into 82 0 times with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 2890.0
Subtract 0 from 82 to get 82.
Include the next digit (5) from the dividend after 82, then repeat: 825 / 248

Step 7:
The number 248 fits into 825 3 times, leaving a remainder of 81.
The next digit of our result is 3. 
Result so far: 28903.0
Deduct 744 from 825 and we're left with 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 248

Advancing to step 8:
If we divide 810 by 248, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 289033.0
Subtracting 744 from 810 leaves us 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.

Moving on to step 9:
248 goes into 660 2 times with a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 289033.2
Deduct 496 from 660 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 10:
When dividing 1640 by 248, we get 6 with a remainder of 152.
The next digit of our result is 6. 
Result so far: 289033.26
The remainder is 152 after subtracting 1488 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
If we divide 1520 by 248, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 289033.266
Subtracting 1488 from 1520 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 289033.266 with a remaining 0.0032.
