Let's divide 28002861 by 9
We're looking to find how many times 9 goes into 28002861.

Moving on to step 1:
9 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 9

Step 2:
28 divided by 9 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 27 away from 28, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 9

Advancing to step 3:
When dividing 10 by 9, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 9 from 10 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 9

Going ahead to step 4:
The number 9 fits into 10 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 311.0
If we subtract 9 from 10, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 9

Let's proceed to step 5:
12 divided by 9 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 3111.0
Subtract 9 from 12 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 9

Step 6:
9 goes into 38 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 31114.0
Deduct 36 from 38 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 9

Let's proceed to step 7:
If we divide 26 by 9, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 311142.0
If we take 18 away from 26, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 9

Going ahead to step 8:
The number 9 fits into 81 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 3111429.0
Subtracting 81 from 81 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.

Moving on to step 9:
When dividing 0 by 9, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3111429.0
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.

Let's proceed to step 10:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3111429.0
If we subtract 0 from 0, we 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.

The final result is 3111429.0 with a remainder of 0.0.
