Let's divide 181099 by 28
The aim is to understand the frequency of 28 in 181099.

Going ahead to step 1:
28 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 28

Moving on to step 2:
28 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 28

Moving on to step 3:
When dividing 181 by 28, we get 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 168 from 181 to get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 28

On to step 4:
The number 28 fits into 130 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 18 after subtracting 112 from 130.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 28

Let's proceed to step 5:
When dividing 189 by 28, we get 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 646.0
If we subtract 168 from 189, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 28

Going ahead to step 6:
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: 6467.0
If we take 196 away from 219, 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.

Advancing to step 7:
28 goes into 230 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 6467.8
If we take 224 away from 230, we end up 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.

Advancing to step 8:
When dividing 60 by 28, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6467.82
Deduct 56 from 60 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.

Moving on to step 9:
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: 6467.821
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.

Advancing to step 10:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 6467.8214
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.

On to step 11:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 6467.82142
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.

Advancing to step 12:
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: 6467.821428
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.

On to step 13:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 6467.8214285
Subtract 140 from 160 to 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.

Let's proceed to step 14:
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: 6467.82142857
If we take 196 away from 200, we end up 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 6467.82142857 and a remainder of 4e-09.
