We look at the division of 74727209 by 310 
The aim is to understand the frequency of 310 in 74727209.

Going ahead to step 1:
The number 310 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 310

Advancing to step 2:
310 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 310

Going ahead to step 3:
310 can be fit into 747 2 times, resulting in a remainder of 127.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 127 after subtracting 620 from 747.
Take the next digit (2) from the dividend and append it to 127, then repeat: 1272 / 310

Going ahead to step 4:
310 can be fit into 1272 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 1240 from 1272 leaves us with 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 310

Moving on to step 5:
The number 310 fits into 327 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 241.0
Subtracting 310 from 327 leaves us with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 310

Advancing to step 6:
When dividing 172 by 310, we get 0 with a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 2410.0
If we subtract 0 from 172, we get 172.
Bring next digit (0) of the dividend behind the 172 and repeat the process: 1720 / 310

Moving on to step 7:
If we divide 1720 by 310, we get 5 and a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 24105.0
If we subtract 1550 from 1720, we get 170.
Grab the next digit (9) from the dividend, add it to 170, then carry on: 1709 / 310

Going ahead to step 8:
The number 310 fits into 1709 5 times, leaving a remainder of 159.
The next digit of our result is 5. 
Result so far: 241055.0
The remainder is 159 after subtracting 1550 from 1709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
When dividing 1590 by 310, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 241055.5
Subtracting 1550 from 1590 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 310 fits into 400 1 times, leaving a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 241055.51
Deduct 310 from 400 and we're left 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.

Advancing to step 11:
900 divided by 310 is 2 with a remainder of 280.
The next digit of our result is 2. 
Result so far: 241055.512
Deduct 620 from 900 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
The number 310 fits into 2800 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 241055.5129
If we subtract 2790 from 2800, we 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.

Moving on to step 13:
310 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 241055.5129
If we take 0 away from 100, we end up 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.

Moving on to step 14:
310 goes into 1000 3 times with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 241055.512903
If we subtract 930 from 1000, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 15:
If we divide 700 by 310, we get 2 and a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 241055.5129032
Subtracting 620 from 700 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
800 divided by 310 is 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 241055.51290322
Subtract 620 from 800 to 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.

The final result is 241055.51290322 with a remainder of 1.8e-07.
