We look at the division of 111043 by 310 
The aim is to understand the frequency of 310 in 111043.

Going ahead to step 1:
310 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 310

Advancing to step 2:
When dividing 11 by 310, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 310

Step 3:
111 divided by 310 is 0 with a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 111 leaves us with 111.
Fetch the next digit (0) from the dividend, attach it to 111 and continue: 1110 / 310

Going ahead to step 4:
If we divide 1110 by 310, we get 3 and a remainder of 180.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 930 from 1110, we get 180.
Append the next digit (4) from the dividend to 180 and continue with: 1804 / 310

Advancing to step 5:
310 goes into 1804 5 times with a remainder of 254.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 1550 from 1804 and we're left with 254.
Grab the next digit (3) from the dividend, add it to 254, then carry on: 2543 / 310

Going ahead to step 6:
The number 310 fits into 2543 8 times, leaving a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 358.0
Subtracting 2480 from 2543 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
If we divide 630 by 310, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 358.2
If we take 620 away from 630, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 310, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 358.2
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
1000 divided by 310 is 3 with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 358.203
Subtracting 930 from 1000 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
310 goes into 700 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 358.2032
If we subtract 620 from 700, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
The number 310 fits into 800 2 times, leaving a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 358.20322
Subtracting 620 from 800 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 358.20322, and the remainder is 0.00018.
