We're dividing 97512995 by 311 
The aim is to understand the frequency of 311 in 97512995.

On to step 1:
The number 311 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 311

On to step 2:
When dividing 97 by 311, we get 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Take the next digit (5) from the dividend and append it to 97, then repeat: 975 / 311

Let's proceed to step 3:
975 divided by 311 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 933 from 975, we get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 311

On to step 4:
311 goes into 421 1 times with a remainder of 110.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 311 from 421 and we're left with 110.
Take the next digit (2) from the dividend and append it to 110, then repeat: 1102 / 311

Advancing to step 5:
If we divide 1102 by 311, we get 3 and a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 313.0
If we take 933 away from 1102, we end up with 169.
Grab the next digit (9) from the dividend, add it to 169, then carry on: 1699 / 311

On to step 6:
When dividing 1699 by 311, we get 5 with a remainder of 144.
The next digit of our result is 5. 
Result so far: 3135.0
If we subtract 1555 from 1699, we get 144.
Fetch the next digit (9) from the dividend, attach it to 144 and continue: 1449 / 311

Going ahead to step 7:
If we divide 1449 by 311, we get 4 and a remainder of 205.
The number 4 becomes the next digit in our result. 
Result so far: 31354.0
Subtract 1244 from 1449 to get 205.
Include the next digit (5) from the dividend after 205, then repeat: 2055 / 311

Going ahead to step 8:
2055 divided by 311 is 6 with a remainder of 189.
The next digit of our result is 6. 
Result so far: 313546.0
The remainder is 189 after subtracting 1866 from 2055.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
311 can be fit into 1890 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 313546.6
Subtract 1866 from 1890 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
The number 311 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 313546.6
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
2400 divided by 311 is 7 with a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 313546.607
Subtracting 2177 from 2400 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 12:
2230 divided by 311 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 313546.6077
Subtracting 2177 from 2230 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 313546.6077 with a remainder of 0.00053.
