We look at the division of 64018239 by 310 
The aim is to understand the frequency of 310 in 64018239.

Let's proceed to step 1:
If we divide 6 by 310, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 310

Let's proceed to step 2:
The number 310 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 310

Going ahead to step 3:
The number 310 fits into 640 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 620 from 640, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 310

On to step 4:
When dividing 201 by 310, we get 0 with a remainder of 201.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 201 after subtracting 0 from 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 310

Advancing to step 5:
If we divide 2018 by 310, we get 6 and a remainder of 158.
Write down 6 as next digit of the result. 
Result so far: 206.0
If we take 1860 away from 2018, we end up with 158.
Take the next digit (2) from the dividend and append it to 158, then repeat: 1582 / 310

Step 6:
When dividing 1582 by 310, we get 5 with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 2065.0
The remainder is 32 after subtracting 1550 from 1582.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 310

Advancing to step 7:
The number 310 fits into 323 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 20651.0
The remainder is 13 after subtracting 310 from 323.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 310

On to step 8:
310 goes into 139 0 times with a remainder of 139.
The next digit of our result is 0. 
Result so far: 206510.0
Deduct 0 from 139 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 9:
310 can be fit into 1390 4 times, resulting in a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 206510.4
If we subtract 1240 from 1390, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
When dividing 1500 by 310, we get 4 with a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 206510.44
The remainder is 260 after subtracting 1240 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 206510.44 and a remainder of 0.26.
