We divide 168535 by 28
The aim is to understand the frequency of 28 in 168535.

On to step 1:
1 divided by 28 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 28

Step 2:
28 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 28

Advancing to step 3:
The number 28 fits into 168 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 168 away from 168, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 28

Step 4:
28 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 60.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 28

On to step 5:
If we divide 53 by 28, we get 1 and a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 601.0
Deduct 28 from 53 and we're left with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 28

Step 6:
When dividing 255 by 28, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 6019.0
Subtracting 252 from 255 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 28, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 6019.1
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
28 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6019.1
Subtract 0 from 20 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.

Advancing to step 9:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 6019.107
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.

Moving on to step 10:
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: 6019.1071
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.

Moving on to step 11:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 6019.10714
If we take 112 away from 120, we end up 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 12:
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: 6019.107142
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.

On to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 6019.1071428
Deduct 224 from 240 and we're left with 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 14:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 6019.10714285
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.

The quotient of the division is 6019.10714285, and the remainder is 2e-08.
