329947 divided by 28 
The aim is to understand the frequency of 28 in 329947.

Going ahead to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 28

On to step 2:
When dividing 32 by 28, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 28 from 32.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 28

Step 3:
49 divided by 28 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 28 from 49 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 28

Let's proceed to step 4:
28 can be fit into 219 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtract 196 from 219 to get 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 28

Let's proceed to step 5:
If we divide 234 by 28, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 1178.0
The remainder is 10 after subtracting 224 from 234.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 28

On to step 6:
If we divide 107 by 28, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 11783.0
Subtracting 84 from 107 leaves us 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:
When dividing 230 by 28, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 11783.8
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.

On to step 8:
If we divide 60 by 28, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 11783.82
Subtracting 56 from 60 leaves us 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.

Step 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 11783.821
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 11783.8214
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 11783.82142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 11783.821428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 11783.8214285
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.

Step 14:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 11783.82142857
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.

The final outcome is 11783.82142857, with a leftover of 4e-09.
