We're dividing 23958780 by 311 
The aim is to understand the frequency of 311 in 23958780.

Step 1:
When dividing 2 by 311, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 311

Going ahead to step 2:
The number 311 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 311

On to step 3:
If we divide 239 by 311, we get 0 and a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 239 leaves us with 239.
Include the next digit (5) from the dividend after 239, then repeat: 2395 / 311

Moving on to step 4:
When dividing 2395 by 311, we get 7 with a remainder of 218.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 2177 away from 2395, we end up with 218.
Bring next digit (8) of the dividend behind the 218 and repeat the process: 2188 / 311

Let's proceed to step 5:
If we divide 2188 by 311, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 2177 from 2188 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 311

Going ahead to step 6:
The number 311 fits into 117 0 times, leaving a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 770.0
Subtracting 0 from 117 leaves us with 117.
Append the next digit (8) from the dividend to 117 and continue with: 1178 / 311

Let's proceed to step 7:
When dividing 1178 by 311, we get 3 with a remainder of 245.
Record the quotient 3 as the next digit in the result. 
Result so far: 7703.0
Subtract 933 from 1178 to get 245.
Fetch the next digit (0) from the dividend, attach it to 245 and continue: 2450 / 311

Step 8:
2450 divided by 311 is 7 with a remainder of 273.
The number 7 becomes the next digit in our result. 
Result so far: 77037.0
Deduct 2177 from 2450 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 9:
2730 divided by 311 is 8 with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 77037.8
The remainder is 242 after subtracting 2488 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 10:
311 goes into 2420 7 times with a remainder of 243.
Record the quotient 7 as the next digit in the result. 
Result so far: 77037.87
The remainder is 243 after subtracting 2177 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 11:
When dividing 2430 by 311, we get 7 with a remainder of 253.
Use 7 as the next digit of our solution. 
Result so far: 77037.877
The remainder is 253 after subtracting 2177 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

The quotient of the division is 77037.877, and the remainder is 0.0253.
