We're dividing 85040255 by 3 
We want to figure out the number of times 85040255 can be divided by 3.

Moving on to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Step 2:
25 divided by 3 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 28.0
If we take 24 away from 25, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Step 3:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
Subtracting 9 from 10 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Going ahead to step 4:
When dividing 14 by 3, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 2834.0
Deduct 12 from 14 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Going ahead to step 5:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 28346.0
Subtract 18 from 20 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Step 6:
If we divide 22 by 3, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 283467.0
Subtract 21 from 22 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Advancing to step 7:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2834675.0
Subtract 15 from 15 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Going ahead to step 8:
If we divide 5 by 3, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 28346751.0
Deduct 3 from 5 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 28346751.6
Subtract 18 from 20 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.

Advancing to step 10:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 28346751.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 28346751.66 and a remainder of 0.002.
