68551213 ÷ 15 
We want to figure out the number of times 68551213 can be divided by 15.

Moving on to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

Advancing to step 2:
68 divided by 15 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 60 from 68 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

Let's proceed to step 3:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 75 from 85 to get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 15

Advancing to step 4:
105 divided by 15 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 457.0
Subtracting 105 from 105 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 15

On to step 5:
15 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 4570.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 15

On to step 6:
15 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 45700.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 15

Moving on to step 7:
121 divided by 15 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 457008.0
The remainder is 1 after subtracting 120 from 121.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 15

Let's proceed to step 8:
If we divide 13 by 15, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 4570080.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 15 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 4570080.8
Subtract 120 from 130 to 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.

Step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 4570080.86
Subtracting 90 from 100 leaves us 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.

Moving on to step 11:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4570080.866
Subtracting 90 from 100 leaves us 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.

The quotient of the division is 4570080.866, and the remainder is 0.001.
