We're dividing 39653360 by 3 
We want to divide 39653360 by 3.

On to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Let's proceed to step 2:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 9 from 9, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Let's proceed to step 3:
If we divide 6 by 3, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we subtract 6 from 6, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Step 4:
If we divide 5 by 3, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1321.0
If we take 3 away from 5, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Moving on to step 5:
23 divided by 3 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 13217.0
The remainder is 2 after subtracting 21 from 23.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Moving on to step 6:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 132177.0
If we subtract 21 from 23, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

On to step 7:
26 divided by 3 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1321778.0
The remainder is 2 after subtracting 24 from 26.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Going ahead to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 13217786.0
If we take 18 away from 20, we end up 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.

Advancing to step 9:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 13217786.6
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.

Going ahead to step 10:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 13217786.66
If we take 18 away from 20, we end up 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.

Our division results in 13217786.66 with a remaining 0.002.
