We look at the division of 28130718 by 235 
The aim is to understand the frequency of 235 in 28130718.

Going ahead to step 1:
When dividing 2 by 235, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 235

On to step 2:
235 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 235

Moving on to step 3:
281 divided by 235 is 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 235 from 281, we get 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 235

Let's proceed to step 4:
235 can be fit into 463 1 times, resulting in a remainder of 228.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 228 after subtracting 235 from 463.
Bring next digit (0) of the dividend behind the 228 and repeat the process: 2280 / 235

On to step 5:
2280 divided by 235 is 9 with a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we take 2115 away from 2280, we end up with 165.
Grab the next digit (7) from the dividend, add it to 165, then carry on: 1657 / 235

Step 6:
1657 divided by 235 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1197.0
Subtracting 1645 from 1657 leaves us with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 235

Let's proceed to step 7:
235 goes into 121 0 times with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 11970.0
If we take 0 away from 121, we end up with 121.
Include the next digit (8) from the dividend after 121, then repeat: 1218 / 235

Advancing to step 8:
When dividing 1218 by 235, we get 5 with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 119705.0
Subtracting 1175 from 1218 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
235 can be fit into 430 1 times, resulting in a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 119705.1
If we take 235 away from 430, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 10:
235 goes into 1950 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 119705.18
If we take 1880 away from 1950, we end up 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.

On to step 11:
235 can be fit into 700 2 times, resulting in a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 119705.182
Subtracting 470 from 700 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
The number 235 fits into 2300 9 times, leaving a remainder of 185.
The number 9 becomes the next digit in our result. 
Result so far: 119705.1829
Subtracting 2115 from 2300 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
1850 divided by 235 is 7 with a remainder of 205.
Use 7 as the next digit of our solution. 
Result so far: 119705.18297
If we subtract 1645 from 1850, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 14:
2050 divided by 235 is 8 with a remainder of 170.
Put 8 as the next digit of the answer. 
Result so far: 119705.182978
The remainder is 170 after subtracting 1880 from 2050.
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 15:
1700 divided by 235 is 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 119705.1829787
The remainder is 55 after subtracting 1645 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 16:
The number 235 fits into 550 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 119705.18297872
Subtracting 470 from 550 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.

The quotient of the division is 119705.18297872, and the remainder is 8e-08.
