Let's divide 703082 by 28
The aim is to understand the frequency of 28 in 703082.

On to step 1:
If we divide 7 by 28, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 28

Moving on to step 2:
70 divided by 28 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 56 away from 70, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 28

Step 3:
143 divided by 28 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 140 from 143, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 28

Step 4:
30 divided by 28 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 251.0
If we take 28 away from 30, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 28

On to step 5:
28 divided by 28 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 2511.0
Subtracting 28 from 28 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 28

Going ahead to step 6:
When dividing 2 by 28, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 25110.0
Subtract 0 from 2 to get 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 7:
20 divided by 28 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25110.0
If we take 0 away from 20, we end up 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.

Moving on to step 8:
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: 25110.07
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.

On to step 9:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 25110.071
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.

Moving on to step 10:
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: 25110.0714
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.

On to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 25110.07142
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.

Moving on to step 12:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 25110.071428
If we take 224 away from 240, we end up 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.

Step 13:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 25110.0714285
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.

Moving on to step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 25110.07142857
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.

Our division results in 25110.07142857 with a remaining 4e-09.
