We divide 862778 by 15
We want to figure out the number of times 862778 can be divided by 15.

Advancing to step 1:
8 divided by 15 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 15

Moving on to step 2:
When dividing 86 by 15, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 11 after subtracting 75 from 86.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 15

Advancing to step 3:
15 goes into 112 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 57.0
The remainder is 7 after subtracting 105 from 112.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 15

On to step 4:
15 can be fit into 77 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
Subtract 75 from 77 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 15

Step 5:
If we divide 27 by 15, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 5751.0
Subtract 15 from 27 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 15

Step 6:
When dividing 128 by 15, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 57518.0
The remainder is 8 after subtracting 120 from 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 15, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 57518.5
The remainder is 5 after subtracting 75 from 80.
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:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 57518.53
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 57518.533
If we subtract 45 from 50, we get 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 57518.533 and a remainder of 0.0005.
