We're dividing 35173418 by 311 
The aim is to understand the frequency of 311 in 35173418.

Let's proceed to step 1:
When dividing 3 by 311, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 311

Step 2:
If we divide 35 by 311, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 311

Going ahead to step 3:
The number 311 fits into 351 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 311 from 351, we get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 311

Going ahead to step 4:
The number 311 fits into 407 1 times, leaving a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 96 after subtracting 311 from 407.
Append the next digit (3) from the dividend to 96 and continue with: 963 / 311

Let's proceed to step 5:
The number 311 fits into 963 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Deduct 933 from 963 and we're left with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 311

Step 6:
311 goes into 304 0 times with a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 1130.0
If we subtract 0 from 304, we get 304.
Fetch the next digit (1) from the dividend, attach it to 304 and continue: 3041 / 311

Step 7:
When dividing 3041 by 311, we get 9 with a remainder of 242.
The number 9 becomes the next digit in our result. 
Result so far: 11309.0
Subtracting 2799 from 3041 leaves us with 242.
Include the next digit (8) from the dividend after 242, then repeat: 2428 / 311

Moving on to step 8:
The number 311 fits into 2428 7 times, leaving a remainder of 251.
Use 7 as the next digit of our solution. 
Result so far: 113097.0
The remainder is 251 after subtracting 2177 from 2428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 9:
2510 divided by 311 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 113097.8
Subtracting 2488 from 2510 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
220 divided by 311 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 113097.8
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
2200 divided by 311 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 113097.807
Deduct 2177 from 2200 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 311, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 113097.807
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
311 goes into 2300 7 times with a remainder of 123.
Record the quotient 7 as the next digit in the result. 
Result so far: 113097.80707
If we subtract 2177 from 2300, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 14:
311 can be fit into 1230 3 times, resulting in a remainder of 297.
The next digit of our result is 3. 
Result so far: 113097.807073
Deduct 933 from 1230 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 15:
When dividing 2970 by 311, we get 9 with a remainder of 171.
The next digit of our result is 9. 
Result so far: 113097.8070739
Deduct 2799 from 2970 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 16:
311 goes into 1710 5 times with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 113097.80707395
Deduct 1555 from 1710 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 113097.80707395, with a leftover of 1.55e-07.
