36840271 ÷ 3 
Let's see how many times 3 fits into 36840271.

Step 1:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

On to step 2:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Step 3:
When dividing 8 by 3, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 6 from 8, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Step 4:
When dividing 24 by 3, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1228.0
Deduct 24 from 24 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Moving on to step 5:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12280.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

On to step 6:
When dividing 2 by 3, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 122800.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Advancing to step 7:
The number 3 fits into 27 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1228009.0
Subtract 27 from 27 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Step 8:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 12280090.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 12280090.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 12280090.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 12280090.33 with a remainder of 0.001.
