We divide 83430 by 28
The aim is to understand the frequency of 28 in 83430.

Going ahead to step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 28

Let's proceed to step 2:
28 can be fit into 83 2 times, resulting in a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 56 from 83 to get 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 28

Moving on to step 3:
274 divided by 28 is 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 252 away from 274, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 28

Let's proceed to step 4:
The number 28 fits into 223 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 297.0
If we take 196 away from 223, we end up with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 28

Step 5:
270 divided by 28 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 2979.0
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 6:
180 divided by 28 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2979.6
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 2979.64
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2979.642
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 2979.6428
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.

Step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 2979.64285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 2979.642857
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 2979.6428571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 2979.64285714
Subtracting 112 from 120 leaves us 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.

The final result is 2979.64285714 with a remainder of 8e-09.
