748563 ÷ 28 
The aim is to understand the frequency of 28 in 748563.

Moving on to step 1:
7 divided by 28 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 28

Step 2:
28 can be fit into 74 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 56 from 74, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 28

Step 3:
When dividing 188 by 28, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 168 from 188, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 28

Going ahead to step 4:
If we divide 205 by 28, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 267.0
Subtract 196 from 205 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 28

On to step 5:
28 can be fit into 96 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 2673.0
Subtracting 84 from 96 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 28

On to step 6:
When dividing 123 by 28, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 26734.0
If we take 112 away from 123, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 28, we get 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 26734.3
The remainder is 26 after subtracting 84 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 28 fits into 260 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 26734.39
If we take 252 away from 260, 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.

On to step 9:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 26734.392
If we take 56 away from 80, we end up 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.

Let's proceed to step 10:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 26734.3928
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.

Let's proceed to step 11:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 26734.39285
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.

Step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 26734.392857
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.

Moving on to step 13:
When dividing 40 by 28, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 26734.3928571
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.

On to step 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 26734.39285714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 26734.39285714, and the remainder is 8e-09.
