We're dividing 89810071 by 311 
The aim is to understand the frequency of 311 in 89810071.

Advancing to step 1:
311 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 311

Step 2:
The number 311 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 311

Going ahead to step 3:
311 goes into 898 2 times with a remainder of 276.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 276 after subtracting 622 from 898.
Take the next digit (1) from the dividend and append it to 276, then repeat: 2761 / 311

Moving on to step 4:
The number 311 fits into 2761 8 times, leaving a remainder of 273.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 2488 from 2761 and we're left with 273.
Append the next digit (0) from the dividend to 273 and continue with: 2730 / 311

Let's proceed to step 5:
The number 311 fits into 2730 8 times, leaving a remainder of 242.
The next digit of our result is 8. 
Result so far: 288.0
If we subtract 2488 from 2730, we get 242.
Grab the next digit (0) from the dividend, add it to 242, then carry on: 2420 / 311

Moving on to step 6:
The number 311 fits into 2420 7 times, leaving a remainder of 243.
Put 7 as the next digit of the answer. 
Result so far: 2887.0
Subtracting 2177 from 2420 leaves us with 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 311

Moving on to step 7:
The number 311 fits into 2437 7 times, leaving a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 28877.0
If we take 2177 away from 2437, we end up with 260.
Fetch the next digit (1) from the dividend, attach it to 260 and continue: 2601 / 311

Moving on to step 8:
2601 divided by 311 is 8 with a remainder of 113.
Record the quotient 8 as the next digit in the result. 
Result so far: 288778.0
Deduct 2488 from 2601 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
311 can be fit into 1130 3 times, resulting in a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 288778.3
The remainder is 197 after subtracting 933 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 10:
311 can be fit into 1970 6 times, resulting in a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 288778.36
Subtract 1866 from 1970 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
When dividing 1040 by 311, we get 3 with a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 288778.363
Deduct 933 from 1040 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 12:
The number 311 fits into 1070 3 times, leaving a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 288778.3633
If we subtract 933 from 1070, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 288778.3633, with a leftover of 0.00137.
