We're dividing 40051349 by 310 
The aim is to understand the frequency of 310 in 40051349.

On to step 1:
When dividing 4 by 310, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 310

Advancing to step 2:
310 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 310

Step 3:
The number 310 fits into 400 1 times, leaving a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 310 from 400 to get 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 310

Moving on to step 4:
When dividing 905 by 310, we get 2 with a remainder of 285.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 285 after subtracting 620 from 905.
Take the next digit (1) from the dividend and append it to 285, then repeat: 2851 / 310

On to step 5:
The number 310 fits into 2851 9 times, leaving a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 61 after subtracting 2790 from 2851.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 310

Advancing to step 6:
The number 310 fits into 613 1 times, leaving a remainder of 303.
Record the quotient 1 as the next digit in the result. 
Result so far: 1291.0
Deduct 310 from 613 and we're left with 303.
Fetch the next digit (4) from the dividend, attach it to 303 and continue: 3034 / 310

Let's proceed to step 7:
The number 310 fits into 3034 9 times, leaving a remainder of 244.
Write down 9 as next digit of the result. 
Result so far: 12919.0
Subtract 2790 from 3034 to get 244.
Include the next digit (9) from the dividend after 244, then repeat: 2449 / 310

Let's proceed to step 8:
The number 310 fits into 2449 7 times, leaving a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 129197.0
If we subtract 2170 from 2449, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 9:
When dividing 2790 by 310, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 129197.9
If we take 2790 away from 2790, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
310 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 129197.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 310 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 129197.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 129197.9 with a balance of 0.0.
