We divide 343331 by 28
The aim is to understand the frequency of 28 in 343331.

Moving on to step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 28

Moving on to step 2:
28 can be fit into 34 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 28 from 34.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 28

Moving on to step 3:
If we divide 63 by 28, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 56 from 63, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 28

Going ahead to step 4:
28 goes into 73 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
The remainder is 17 after subtracting 56 from 73.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 28

Let's proceed to step 5:
173 divided by 28 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 1226.0
If we subtract 168 from 173, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 28

Advancing to step 6:
When dividing 51 by 28, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 12261.0
If we take 28 away from 51, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
If we divide 230 by 28, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 12261.8
Subtract 224 from 230 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
28 can be fit into 60 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12261.82
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 28 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 12261.821
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 12261.8214
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
28 goes into 80 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12261.82142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12261.821428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 12261.8214285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
28 goes into 200 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 12261.82142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 12261.82142857 and a remainder of 4e-09.
