We divide 4486 by 28
The aim is to understand the frequency of 28 in 4486.

Let's proceed to step 1:
4 divided by 28 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 28

On to step 2:
If we divide 44 by 28, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 28 from 44 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 28

Let's proceed to step 3:
The number 28 fits into 168 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 0 after subtracting 168 from 168.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 28

Moving on to step 4:
The number 28 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 6 leaves us with 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 5:
28 goes into 60 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 160.2
If we subtract 56 from 60, 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.

Going ahead to step 6:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 160.21
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.

Let's proceed to step 7:
When dividing 120 by 28, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 160.214
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.

Going ahead to step 8:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 160.2142
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.

Moving on to step 9:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 160.21428
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.

Moving on to step 10:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 160.214285
Deduct 140 from 160 and we're left 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.

Step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 160.2142857
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.

Let's proceed to step 12:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 160.21428571
Subtracting 28 from 40 leaves us 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 160.21428571 with a balance of 1.2e-08.
