We're dividing 75933603 by 311 
The aim is to understand the frequency of 311 in 75933603.

Step 1:
If we divide 7 by 311, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 311

Step 2:
311 goes into 75 0 times with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 311

On to step 3:
311 can be fit into 759 2 times, resulting in a remainder of 137.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 622 from 759 to get 137.
Append the next digit (3) from the dividend to 137 and continue with: 1373 / 311

Going ahead to step 4:
When dividing 1373 by 311, we get 4 with a remainder of 129.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 1244 from 1373 leaves us with 129.
Bring next digit (3) of the dividend behind the 129 and repeat the process: 1293 / 311

On to step 5:
311 can be fit into 1293 4 times, resulting in a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 244.0
Deduct 1244 from 1293 and we're left with 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 311

Going ahead to step 6:
If we divide 496 by 311, we get 1 and a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 2441.0
If we take 311 away from 496, we end up with 185.
Append the next digit (0) from the dividend to 185 and continue with: 1850 / 311

Advancing to step 7:
311 goes into 1850 5 times with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 24415.0
If we subtract 1555 from 1850, we get 295.
Bring next digit (3) of the dividend behind the 295 and repeat the process: 2953 / 311

Advancing to step 8:
The number 311 fits into 2953 9 times, leaving a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 244159.0
Deduct 2799 from 2953 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
311 can be fit into 1540 4 times, resulting in a remainder of 296.
The next digit of our result is 4. 
Result so far: 244159.4
If we subtract 1244 from 1540, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 10:
If we divide 2960 by 311, we get 9 and a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 244159.49
If we subtract 2799 from 2960, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 11:
311 goes into 1610 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 244159.495
If we subtract 1555 from 1610, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
550 divided by 311 is 1 with a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 244159.4951
Subtract 311 from 550 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 13:
2390 divided by 311 is 7 with a remainder of 213.
Put 7 as the next digit of the answer. 
Result so far: 244159.49517
Subtract 2177 from 2390 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 14:
When dividing 2130 by 311, we get 6 with a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 244159.495176
Deduct 1866 from 2130 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 15:
The number 311 fits into 2640 8 times, leaving a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 244159.4951768
Subtract 2488 from 2640 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 16:
311 goes into 1520 4 times with a remainder of 276.
The next digit of our result is 4. 
Result so far: 244159.49517684
If we take 1244 away from 1520, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final outcome is 244159.49517684, with a leftover of 2.76e-07.
