We look at the division of 30715256 by 355 
The aim is to understand the frequency of 355 in 30715256.

Let's proceed to step 1:
355 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 355

Step 2:
The number 355 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 355

Advancing to step 3:
If we divide 307 by 355, we get 0 and a remainder of 307.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 307, we end up with 307.
Fetch the next digit (1) from the dividend, attach it to 307 and continue: 3071 / 355

Step 4:
3071 divided by 355 is 8 with a remainder of 231.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 2840 from 3071 and we're left with 231.
Include the next digit (5) from the dividend after 231, then repeat: 2315 / 355

Moving on to step 5:
355 goes into 2315 6 times with a remainder of 185.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 2130 from 2315 and we're left with 185.
Bring next digit (2) of the dividend behind the 185 and repeat the process: 1852 / 355

Moving on to step 6:
1852 divided by 355 is 5 with a remainder of 77.
Put 5 as the next digit of the answer. 
Result so far: 865.0
Subtracting 1775 from 1852 leaves us with 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 355

Let's proceed to step 7:
If we divide 775 by 355, we get 2 and a remainder of 65.
The next digit of our result is 2. 
Result so far: 8652.0
The remainder is 65 after subtracting 710 from 775.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 355

On to step 8:
355 can be fit into 656 1 times, resulting in a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 86521.0
Deduct 355 from 656 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 9:
355 can be fit into 3010 8 times, resulting in a remainder of 170.
The next digit of our result is 8. 
Result so far: 86521.8
Deduct 2840 from 3010 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
355 can be fit into 1700 4 times, resulting in a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 86521.84
If we take 1420 away from 1700, we end up 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.

On to step 11:
When dividing 2800 by 355, we get 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 86521.847
Subtracting 2485 from 2800 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 12:
355 can be fit into 3150 8 times, resulting in a remainder of 310.
Use 8 as the next digit of our solution. 
Result so far: 86521.8478
Subtracting 2840 from 3150 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 13:
355 can be fit into 3100 8 times, resulting in a remainder of 260.
Record the quotient 8 as the next digit in the result. 
Result so far: 86521.84788
Subtracting 2840 from 3100 leaves us with 260.
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 86521.84788 and a remainder of 0.00026.
