We divide 83686449 by 3
We want to divide 83686449 by 3.

Going ahead to step 1:
8 divided by 3 is 2 with 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.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Going ahead to step 2:
23 divided by 3 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 21 away from 23, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Moving on to step 3:
3 goes into 26 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 278.0
Deduct 24 from 26 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Step 4:
If we divide 28 by 3, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 2789.0
Subtracting 27 from 28 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Step 5:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 27895.0
Subtract 15 from 16 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Advancing to step 6:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 278954.0
If we take 12 away from 14, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

On to step 7:
When dividing 24 by 3, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2789548.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Let's proceed to step 8:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 27895483.0
Subtracting 9 from 9 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.

Step 9:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 27895483.0
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.

Advancing to step 10:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 27895483.0
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.

The quotient of the division is 27895483.0, and the remainder is 0.0.
