We divide 358189 by 28
The aim is to understand the frequency of 28 in 358189.

Step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 28

Step 2:
The number 28 fits into 35 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 28 from 35 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 28

Going ahead to step 3:
28 can be fit into 78 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 56 away from 78, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 28

On to step 4:
If we divide 221 by 28, we get 7 and a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 127.0
Deduct 196 from 221 and we're left with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 28

On to step 5:
258 divided by 28 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1279.0
Subtract 252 from 258 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 28

Moving on to step 6:
28 can be fit into 69 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 12792.0
The remainder is 13 after subtracting 56 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 28, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 12792.4
The remainder is 18 after subtracting 112 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
If we divide 180 by 28, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12792.46
Deduct 168 from 180 and we're left 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.

Step 9:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 12792.464
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.

Advancing to step 10:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12792.4642
Subtracting 56 from 80 leaves us 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.

Moving on to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12792.46428
Subtract 224 from 240 to 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.

Step 12:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 12792.464285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 12792.4642857
Subtracting 196 from 200 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.

On to step 14:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 12792.46428571
Deduct 28 from 40 and we're left 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.

In conclusion, the division gives 12792.46428571 with a balance of 1.2e-08.
