783353 ÷ 15 
Our goal is to divide 783353 by 15.

Advancing to step 1:
15 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 15

Advancing to step 2:
When dividing 78 by 15, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 75 from 78 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 15

Moving on to step 3:
When dividing 33 by 15, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 30 away from 33, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 15

Advancing to step 4:
The number 15 fits into 33 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 522.0
Deduct 30 from 33 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 15

Step 5:
If we divide 35 by 15, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 5222.0
Subtracting 30 from 35 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 15

Advancing to step 6:
15 can be fit into 53 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 52223.0
If we take 45 away from 53, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 15, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 52223.5
Subtracting 75 from 80 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 52223.53
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 52223.533
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 52223.533 and a remainder of 0.0005.
