We're dividing 42300217 by 310 
The aim is to understand the frequency of 310 in 42300217.

Let's proceed to step 1:
The number 310 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 310

Advancing to step 2:
310 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 310

Step 3:
If we divide 423 by 310, we get 1 and a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 310 from 423 and we're left with 113.
Bring next digit (0) of the dividend behind the 113 and repeat the process: 1130 / 310

Step 4:
1130 divided by 310 is 3 with a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 930 away from 1130, we end up with 200.
Bring next digit (0) of the dividend behind the 200 and repeat the process: 2000 / 310

Advancing to step 5:
310 goes into 2000 6 times with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtract 1860 from 2000 to get 140.
Take the next digit (2) from the dividend and append it to 140, then repeat: 1402 / 310

Let's proceed to step 6:
When dividing 1402 by 310, we get 4 with a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 1364.0
Subtract 1240 from 1402 to get 162.
Append the next digit (1) from the dividend to 162 and continue with: 1621 / 310

On to step 7:
The number 310 fits into 1621 5 times, leaving a remainder of 71.
Record the quotient 5 as the next digit in the result. 
Result so far: 13645.0
Subtract 1550 from 1621 to get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 310

Going ahead to step 8:
If we divide 717 by 310, we get 2 and a remainder of 97.
The next digit of our result is 2. 
Result so far: 136452.0
Subtracting 620 from 717 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
If we divide 970 by 310, we get 3 and a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 136452.3
Subtract 930 from 970 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 310 fits into 400 1 times, leaving a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 136452.31
Subtracting 310 from 400 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
If we divide 900 by 310, we get 2 and a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 136452.312
If we subtract 620 from 900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
310 can be fit into 2800 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 136452.3129
Subtract 2790 from 2800 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 310, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 136452.3129
Deduct 0 from 100 and we're left with 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 14:
If we divide 1000 by 310, we get 3 and a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 136452.312903
Deduct 930 from 1000 and we're left 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 15:
700 divided by 310 is 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 136452.3129032
The remainder is 80 after subtracting 620 from 700.
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 16:
When dividing 800 by 310, we get 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 136452.31290322
If we subtract 620 from 800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 136452.31290322 and a remainder of 1.8e-07.
