We divide 66783433 by 15
Our goal is to divide 66783433 by 15.

On to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 15

On to step 2:
If we divide 66 by 15, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 60 from 66 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 15

Step 3:
When dividing 67 by 15, we get 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 60 from 67, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 15

Moving on to step 4:
78 divided by 15 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 445.0
If we take 75 away from 78, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 15

Going ahead to step 5:
If we divide 33 by 15, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 4452.0
The remainder is 3 after subtracting 30 from 33.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 15

Moving on to step 6:
15 can be fit into 34 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 44522.0
If we take 30 away from 34, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

Advancing to step 7:
15 can be fit into 43 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 445222.0
The remainder is 13 after subtracting 30 from 43.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 15

Let's proceed to step 8:
When dividing 133 by 15, we get 8 with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 4452228.0
If we take 120 away from 133, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
15 can be fit into 130 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 4452228.8
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
15 goes into 100 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4452228.86
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4452228.866
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4452228.866 and a remainder of 0.001.
