We divide 28668385 by 10
The aim is to understand the frequency of 10 in 28668385.

Advancing to step 1:
When dividing 2 by 10, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 10

Going ahead to step 2:
When dividing 28 by 10, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 20 from 28 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 10

Moving on to step 3:
The number 10 fits into 86 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 80 from 86, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 10

Let's proceed to step 4:
The number 10 fits into 66 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 286.0
If we subtract 60 from 66, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 10

Moving on to step 5:
10 can be fit into 68 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 2866.0
If we take 60 away from 68, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 10

Moving on to step 6:
83 divided by 10 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 28668.0
Subtracting 80 from 83 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 10

Moving on to step 7:
38 divided by 10 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 286683.0
If we take 30 away from 38, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 10

Step 8:
The number 10 fits into 85 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 2866838.0
Subtract 80 from 85 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
10 goes into 50 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2866838.5
Deduct 50 from 50 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.

Let's proceed to step 10:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2866838.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2866838.5
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.

The quotient of the division is 2866838.5, and the remainder is 0.0.
