Let's divide 20321798 by 28
The aim is to understand the frequency of 28 in 20321798.

Step 1:
The number 28 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 28

Advancing to step 2:
The number 28 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 28

Moving on to step 3:
When dividing 203 by 28, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 196 from 203, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 28

Step 4:
When dividing 72 by 28, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we take 56 away from 72, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 28

Step 5:
When dividing 161 by 28, we get 5 with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 725.0
If we subtract 140 from 161, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 28

Moving on to step 6:
28 goes into 217 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 7257.0
Deduct 196 from 217 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 28

On to step 7:
28 can be fit into 219 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 72577.0
If we subtract 196 from 219, we get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 28

On to step 8:
28 goes into 238 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 725778.0
Subtracting 224 from 238 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
When dividing 140 by 28, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 725778.5
Deduct 140 from 140 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 725778.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
28 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 725778.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 725778.5 and a remainder of 0.0.
